### What?
This PR adds an hourly workflow that will update the test manifest used when testing with Turbopack.
### Why?
To ensure we don't regress any test suites.
### How?
I use the existing `scripts/update-fonts-data-workflow.js` workflow script which will execute a script, then create a PR with the current working tree. If any pending automated PRs exist, they will be closed when a new one is opened.
