"This extension has a Pre-Release version available" link is confusing

Testing #138068

When I click this it triggers a reload of the lower half of the extension details page (I presume if there were a difference there in the pre-release version it'd show up here), but things like the version number don't change, and the link doesn't go away. I get that in some cases the README for the pre-release version might have relevant info, but I feel like in many cases this will cause more confusion than benefit.

Also, no obvious way to get back to seeing the information for the Release version.

@gjsjohnmurray There is an action in the dropdown of gear icon to Show the Pre-Release version.

See proposal from @weinand in #138264

I like the idea from @weinand in #138264 - This needs some UX exploration and study. Hence postponed that to next release.

For this release, I fixed the current flow

• Removed the Pre-Release version link in favor of Show Pre-Release / Release version actions in gear icon.
• Fixed extension editor to show the asked version
