Subject: [PATCH] .github: update flakehub workflow to support existing tags
 (#9067)

This adds a workflow_dispatch input to the update-flakehub workflow that
allows the user to specify an existing tag to publish to FlakeHub. This
is useful for publishing a version of a package that has already been
tagged in the repository.

Updates #9008
