Browser interface allows forking to an owned grup.
This commit brings API up to speed by providing optional namespace
parameter to fork API. This allows forking to users and groups under
forker's control using their id or unique name.

Fixes #21591

Reduce intermittent spec failures by making VueJS resource interceptor decrement outstanding resource counts when HTTP response is received

Before the count would be reduced 500 ms after a DOM update tick, which could cause race conditions since the `DatabaseCleaner` could run in the middle of a Rails controller handling the response.

Partial fix to #21197 and other intermittent spec failures.

See merge request !6224

Removed `margin-bottom`

Corrected commit-actions margin

Reverted action margin for a more logical approach

Change "check out, review, and merge locally" URL to SSH by default.

## What does this MR do?

Change the default URL type  in the "Check out, review, and merge locally" pop-up dialog to SSH.

## Why was this MR needed?

The default URL to show on the project screen is the SSH URL, so it makes sense for it to be the default here too. Plus, since most people (hopefully) use SSH keys to avoid typing credentials repeatedly, changing this default means these commands can be pasted into a terminal more easily since no password prompt will get in the way.

Using the default protocol here (vs HTTP only) is more convenient
when it comes to pasting these commands into a terminal.

This allows us to take advantage of
