swift-syntax Fix Bazel build

Building with Bazel doesn't work at the moment. That's mainly due to the missing dependencies for SwiftRefactorTest and SwiftSyntaxMacros. However, there is also an issue with rules_python which gets fixed by the update of the Bazel version.

To alleviate the risk of causing an outdated Bazel configuration again, I also added an action that at least builds everything in PRs.

Probably need to clone the repo in the build job as well ... 🤦‍♂️

cc @ahoppen is it ok to add a non-blocking job for this?

I’m personally fine with running the Bazel tests in GitHub Actions (thanks for adding them) but I’d like to hear @bnbarham’s opinion as well before merging.
