Automate creating a PR for version bump

I wasn't able to make a PR that merged in the changes because of our branch protection rules.

There are ways to bypass them but I think we'd have to create a specific app in order for us to target the bypass.

Instead I thought an easier first step would be to automate creating a PR instead
