* Removes any surrounding paragraph nodes
* And transfers any attributes from the surrounding paragraph down to the image node
* Adds IsBlock and Ordinal (zero based) field to the image context passed to the image render hooks
IsBlock is set to true if `wrapStandAloneImageWithinParagraph = false` and the image's parent node has only one child.

E.g.:
```
> foo
> bar
{.myclass}
```
There are some current limitations: For tables you can currently only apply it to the full table, and for lists the ul/ol-nodes only, e.g.:
```
* Fruit
* Apple
* Orange
* Banana
{.fruits}
* Dairy
* Milk
* Cheese
{.dairies}
{.list}
```
Fixes#7548
You can turn off this behaviour:
```toml
[markup]
[markup.goldmark]
[markup.goldmark.parser]
autoHeadingIDAsciiOnly = true
```
Note that the `anchorize` now adapts its behaviour depending on the default Markdown handler.
Fixes#6616
This commit adds the fast and CommonMark compliant Goldmark as the new default markdown handler in Hugo.
If you want to continue using BlackFriday as the default for md/markdown extensions, you can use this configuration:
```toml
[markup]
defaultMarkdownHandler="blackfriday"
```
