Add missing routes to make group edits work
6b90ccb9fd changed the routes so that users/groups can be accessed via`/:id`, but the Rails `form_for` method expects to use the `groups#show` path helper for the form action URL. This causes group edits and deletes to fail because the PUT/PATCH/DELETE methods did not exist for `/:id`. This MR adds these methods so that `form_for` continues to work.
Closes#23306

Allow browsing branches that end with '.atom'
## What does this MR do?
1. Simplify the regex capture in the routing for the CommitsController
to not exclude the '.atom' suffix. That's a perfectly valid git
branch name, so we shouldn't blow up if we get it.
2. Because Rails now can't automatically detect the request format, add
some code to do so in `ExtractPath` when there is no path. This means
that, given branches 'foo' and 'foo.atom', the Atom feed for the
former is unroutable. To fix this: don't do that! Give the branches
different names!
## Why was this MR needed?
Creating a branch or tag name ending in '.atom' would cause some 500s on that repo.
## What are the relevant issue numbers?
Closes#21955. Related to !5994.
See merge request !6750
We need to do two things to support this:
1. Simplify the regex capture in the routing for the CommitsController
to not exclude the '.atom' suffix. That's a perfectly valid git
branch name, so we shouldn't blow up if we get it.
2. Because Rails now can't automatically detect the request format, add
some code to do so in `ExtractPath` when there is no path. This means
that, given branches 'foo' and 'foo.atom', the Atom feed for the
former is unroutable. To fix this: don't do that! Give the branches
