$(date +%Y-%m-%d) Dependency Update Errors

[github-actions]

mypy check failed
Backend tests failed.

This is coming from the dependency check workflow. We need the date to be formatted correctly in the issue title, and on top of that it seems like the error message isn't being formatted correctly. It'd also be nice to get the update dependencies reported here so we know what's being changed to cause the tests to fail.
