refactor: bump azure template and formula directly on release

Rather than try and do something fancy on tag creation via workflows - which won't trigger due to workflows not being able to trigger other workflows without using workflow_run on the downstream workflow as a trigger - we just do all the releasing at once. This makes it easy to understand whether a release fully completed.
