Create GitHub action to automatically bump to a -dev version after a release is tagged.
On a branch:
- The bump will always be a z bump on branches
- If the bump is to an RC, then the bump will be back down to dev (ie, 9.9.0-rc1 to 9.9.0-dev)
- If the bump is not an RC, the bump wil be up to dev (ie, 9.9.0 to 9.9.1-dev)
On main:
- If the X.Y version on main is smaller than the X.Y on the release tag, this action will open a PR to bump the version on main to the release tag's X.Y+1
- Major version (X) dev bumps will still need to be manual
