## Testing

- [ ] Added/updated automated tests
- [X] QA'd all new/changed functionality manually
- I ran the updated snapshot action on this branch and verified that it
pushed the branch-tagged image, but not the SHA-tagged one.
- I ran the cleanup script in dry-run mode and verified that it didn't
expect to delete any non-sha-tagged images
- I wasn't able to test the delete-image-on-branch-delete action for
obvious reasons.
- I haven't tested the cleanup script in non-dry-run mode... I could do
on my personal dockerhub...
