Error when trying to create the release pull request commit for googleapis/google-cloud-java:

Error while creating a tree and updating the ref: Sorry, your request timed out.  It's likely that your input was too large to process.  Consider building the tree incrementally, or building the commits you need in a local clone of the repository and then pushing them to GitHub.

It's trying to update a ton of files in a single commit which turns out is too big for the GitHub API. We should be able to break this apart into multiple commits (maybe 50 file updates per commit?)
