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:

GitHub allows defining a default shell for all jobs on the workflow
level, which we did not use before, yet practically did when it comes
down to our usage of `named::bash`. Since this makes stuff quite
verbose, I decided on using the defaults instead so the workflows become
somewhat easier to audit when reading the generated files.
Powershell steps continue to use Powershell, only the default for bash
scripts was modified.
