Create new Framework tab and basic framework report table

What does this MR do and why?

This follows Rename Framework tab to Projects (!131838 - merged), permanently changing the Framework tab to Projects and then creating the new Framework tab, with basic table, behind the feature flag.

The next MR will expand on the table to add framework pills and associated projects.

Screenshots or screen recordings

Screenshots are required for UI changes, and strongly recommended for all other merge requests.
