Check we're on the right branch before tagging, and on the right tag before uploading
* Abort if we're on the wrong branch
* Check we have the right tag checked out
* Clarify that `publish` only releases to GitHub
* rename major/minor into the right semver terminology minor/patch (since this was something that got me very confused the first couple of times I've used the script)
* name the release branch based on the new version, not the previous one
With the prior format, 1.33.0 / 1.33.1 / 1.33.2 got separate branches:
release-v1.33.0
release-v1.33.1
release-v1.33.2
Under the new model, all three would share a common branch:
release-v1.33
As before, RCs and actual releases exist as tags on these branches.
This better reflects our support model, e.g., that the "1.33" series had
a formal release followed by two patches / updates.
