The template packages are based on go1.20.5 with the patch in befec5ddbbfbd81ec84e74e15a38044d67f8785b added.
This also includes a security fix that now disallows Go template actions in JS literals (inside backticks).
This will throw an error saying "... appears in a JS template literal".
If you're really sure this isn't a security risk in your case, you can revert to the old behaviour:
```toml
[security]
[security.gotemplates]
allowActionJSTmpl = true
```

This commit replaces the main part of `helpers.StripHTML` with Go's implementation in its html/template package.
It's a little slower, but correctness is more important:
```bash

BenchmarkStripHTMLNew-10 384520 3099 ns/op 2089 B/op 10 allocs/op
```
