Part of #32878

Add tests
Update empty state
[ci skip]

- Cleans the fork project layout by removing the grid & reverting back
to full flexbox to allow for the layout to correctly expand.
- Removes duplicated markup
- Fixes a bug where the forked project would trigger the load indicator

Previously the fork button was disabled for all users if they have
exceeded their project limit. This fixes that by changing the check
to see if the user can fork to a group instead of their own namespace.

This behaviour is already possible by visiting the new fork page
directly, so this just fixes the button being disabled.

Closes #38462
