This is a small fix to the alpha release script to run it any time we're not on a release-* branch or a master branch. Rather than only if we're pointing the pr at dev.

I think this is better because it defaults on the side of publishing alpha releases rather than not doing anything.

The logic is as follows:

• Build on master branch with new versions in package.json will publish full release
• Build on PR with branch named release- will publish a release candidate.
• Every other PR will build and publish an alpha npm release.

I'm going to add this to v10 #354
