The main topic of this commit is that you can now index fragments (content heading identifiers) when calling `.Related`.
You can do this by:
* Configure one or more indices with type `fragments`
* The name of those index configurations maps to an (optional) front matter slice with fragment references. This allows you to link
page<->fragment and page<->page.
* This also will index all the fragments (heading identifiers) of the pages.
It's also possible to use type `fragments` indices in shortcode, e.g.:
```
{{ $related := site.RegularPages.Related .Page }}
```
But, and this is important, you need to include the shortcode using the `{{<` delimiter. Not doing so will create infinite loops and timeouts.
This commit also:
* Adds two new methods to Page: Fragments (can also be used to build ToC) and HeadingsFiltered (this is only used in Related Content with
index type `fragments` and `enableFilter` set to true.
* Consolidates all `.Related*` methods into one, which takes either a `Page` or an options map as its only argument.
* Add `context.Context` to all of the content related Page API. Turns out it wasn't strictly needed for this particular feature, but it will
soon become usefil, e.g. in #9339.

So you can do `process.env.HUGO_PUBLISHDIR` in your `postcss.config.js` to figure out where Hugo publishes
its files.
Note that the value will always be an absolute file path and will point to a directory on disk even when running `hugo server` in memory mode.
If you write to this folder from PostCSS when running the server, you could run the server with one of these flags:
```
hugo server --renderToDisk
hugo server --renderStaticToDisk
```

This is how it may look like with a extended build:
```
hugo v0.107.0-6445b1e9ff963b07c55d9d69cb9abef8ef21fc5d+extended darwin/arm64 BuildDate=2022-12-06T11:21:50Z
GOOS="darwin"
GOARCH="arm64"
GOVERSION="go1.19.3"
github.com/sass/libsass="3.6.5"
github.com/webmproject/libwebp="v1.2.4"

github.com/sass/dart-sass-embedded/implementation="1.56.1"
```
Note that this has only been a problem with "raw dates" in TOML files in /data and similar. The predefined front matter
dates `.Date` etc. are converted to a Go Time and has worked fine even after upgrading to v2 of the go-toml lib.

* Record the leading whitespace (tabs, spaces) before the shortcode when parsing the page.
* Apply that indentation to the rendered result of shortcodes without inner content (where the user will apply indentation).
Fixes#9946
Note that we will now fail if `inlineImports` is enabled and we cannot resolve an import.
You can work around this by either:
* Use url imports or imports with media queries.
* Set `skipInlineImportsNotFound=true` in the options
Also get the argument order in the different NewFileError* funcs in line.
Fixes#9895
* Redo the server error template
* Always add the content file context if relevant
* Remove some now superflous error string matching
* Move the server error template to _server/error.html
* Add file context (with position) to codeblock render blocks
* Improve JS build errors
Fixes#9892Fixes#9891Fixes#9893
We cannot (also, it doesn't add any value) use that when the `clock` is set,
* To measure time (before that global is set)
* To compare file timestamps re cache eviction
Fixes#9868
* Add file context to minifier errors when publishing
* Misc fixes (see issues)
* Allow custom server error template in layouts/server/error.html
To get to this, this commit also cleans up and simplifies the code surrounding errors and files. This also removes the usage of `github.com/pkg/errors`, mostly because of https://github.com/pkg/errors/issues/223 -- but also because most of this is now built-in to Go.

If set, `key` will be used as the only cache key element for the resource.
The default behaviour is to calculate the key based on the URL and all the options.
This means that you can now do:
```
{{ $cacheKey := print $url (now.Format "2006-01-02") }}
{{ $resource := resource.GetRemote $url (dict "key" $cacheKey) }}
```
Fixes#9755
And make both .Resources and resources implement it.
This gets us 2 new methods/functions, so you can now also do:
* .Resources.Get
* resources.ByType
Note that GetRemote is not covered by this interface, as that is only available as a global template function.
Fixes#8653
This commit prevents the most commons case of infinite recursion in link render hooks when the `linkify` option is enabled (see below). This is always a user error, but getting a `stack overflow` (the current stack limit in Go is 1 GB on 64-bit, 250 MB on 32-bit) error isn't very helpful. This fix will not prevent all such errors, though, but we may do better once #9570 is in place.
So, these will fail:
```
<a href="{{ .Destination | safeURL }}" >{{ .Text | markdownify }}</a>
<a href="{{ .Destination | safeURL }}" >{{ .Text | .Page.RenderString }}</a>
```
`.Text` is already rendered to `HTML`. The above needs to be rewritten to:
```
<a href="{{ .Destination | safeURL }}" >{{ .Text | safeHTML }}</a>
<a href="{{ .Destination | safeURL }}" >{{ .Text | safeHTML }}</a>
```
Fixes#8959
