Subject: [PATCH] Merges to main don't get posted to main && it should be
 clearer how branches are deployed (#415)

* fixes #319 - merges to main still don't get posted to /main , and #362 It should be clearer how branches are deployed -- move to using 'pull_request' instead of 'push' (we can't push to master directly anyhow), and run on 'closed'; also add comment on PR itself
* updating to add subsequent pushes to the same PR
