extension_ci: Merge extension workflow files into one file (#48810)

This PR consolidates the two workflow files shipped to extensions into
one, which stops us from requiring a separate runner for what can
actually be done in one workflow.

It also
- adds a check that version bumps will now only be created by zed-zippy
in separate commits.
- Makes the bumping of versions faster and more reliable.
- (Hopefully) fixes an issue we were seeing in some CI tests.

Release Notes:

- N/A
