Improve or remove New Workspace button in the Prebuild page

[jankeromnes]

Follow-up to #5474

In the Prebuild page, there is a New Workspace button, with the intent to allow starting workspaces from a Prebuild.

Currently, the button opens the original context URL of the Prebuild (e.g. a branch, or a Pull Request URL). However, this is no longer the correct link if new commits have been pushed to the original branch.

We could either:

• Better explain what the New Workspace button does and doesn't
• Point the New Workspace button more precisely to a specific Prebuild, e.g. by linking to the original full commit URL that this Prebuild was built for
• Remove the New Workspace button

Suggestion to remove: #5474 (comment)

One question to the New Workspace button on the Prebuild page: is it practical? You cannot start a workspace for old prebuilds anyways, so the page is more of a view. Wdyt of removing it from there?

Suggestion to keep and rename the button: #5474 (comment)

I'd opt to leave it here. I was just using it and didn't have any doubts that it was handy there. It should maybe show what it does (Open workspace on branch branch-name) in the tooltip.

Suggestion to link to a commit context URL: #5474 (comment)

Or, we can still link to the exact (potentially outdated) prebuild by using the commit context URL.

But maybe after using it for a bit we'll know more about what's better here.
