Display group/project access requesters separately in admin
## What does this MR do?
It displays the access requesters in a separate list in group & project members pages.
It also harmonize the members counter UI to use `%span.badge` everywhere (in the admin & non-admin members views).
## Are there points in the code the reviewer needs to double check?
No.
## Why was this MR needed?
To not confuse access requesters with actual members.
## What are the relevant issue numbers?
Closes#18871.

See merge request !4432
- Need to pass in a `page_slug` to the filter, so it can rewrite based
on the current page (all links are rewritten to the level of the app root).
- The earlier `markdown_preview` endpoint was at the level of the wiki.
We need to know the current page (for rewriting, as above), so this
commit moves the endpoint to the level of a wiki page.
- Fix all tests
