* Fixes for new CI pipeline (Github Actions)
- Support ci skip tag on commits to avoid build dupes
- Add smarter path detection so we don't spam tons of tests
- Allow steps to cancel if previous steps were cancelled (don't always
run)
- Separate workflows to be more modular
- Update release workflow to do a few more things
- Add helpful messages
- Be more strict in version checking (now with added regex)
- Make changelog smarter about when to trigger
- Add some functionality for changelog to handle releases and
prereleases separately
- Better error handling
- Split up the version validation and the release to make way for more
releases
* add step in workflow to merge to release branch after a release
* add check for git diff so commit doesn't error out constantly
