Gusted 542281ab9f disallow javascript: URI in the repository description 
- Fixes an XSS that was introduced in
https://codeberg.org/forgejo/forgejo/pulls/1433
- This XSS allows for `href`s in anchor elements to be set to a
`javascript:` uri in the repository description, which would upon
clicking (and not upon loading) the anchor element execute the specified
javascript in that uri.
- [`AllowStandardURLs`](https://pkg.go.dev/github.com/microcosm-cc/bluemonday#Policy.AllowStandardURLs) is now called for the repository description
policy, which ensures that URIs in anchor elements are `mailto:`,
`http://` or `https://` and thereby disallowing the `javascript:` URI.
It also now allows non-relative links and sets `rel="nofollow"` on
anchor elements.
- Unit test added.

(cherry picked from commit bb448f3dc2)

Use restricted sanitizer for repository description (#28141) 
- Currently the repository description uses the same sanitizer as a
normal markdown document. This means that element such as heading and
images are allowed and can be abused.
- Create a minimal restricted sanitizer for the repository description,
which only allows what the postprocessor currently allows, which are
links and emojis.
- Added unit testing.
- Resolves https://codeberg.org/forgejo/forgejo/issues/1202
- Resolves https://codeberg.org/Codeberg/Community/issues/1122

(cherry picked from commit 631c87cc23)

Render plaintext task list items for markdown files (#26186) 
- The library that's being used for org-mode, [doesn't render the status
of list items](https://github.com/niklasfasching/go-org/issues/63).
- Add a modified version of the proposed CSS snippet to still display
the status for the list items. The alternative was parsing HTML and
transforming it, which is too complicated for this small task.
- Resolves https://codeberg.org/Codeberg/Community/issues/1099

(cherry picked from commit 9753c7e4b8)

Allow all URL schemes in Markdown links by default (#24805) 
- Closes #21146
- Closes #16721

## ⚠️ BREAKING ⚠️
This changes the default behavior to now create links for any URL scheme
when the user uses the markdown form for links (`[label](URL)`), this
doesn't affect the rendering of inline links. To opt-out set the
`markdown.CUSTOM_URL_SCHEMES` setting to a list of allowed schemes, all
other schemes (except `http` and `https`) won't be allowed.
