fix: Allow protobuf 6.x (#2142)

* fix: Allow protobuf 6.x

* update prerelease_deps nox session so that prerelease versions of protobuf are installed

* ensure python-bigquery is installed from source

* feat: add support for Python 3.13

* restore replacement

* 🦉 Updates from OwlBot post-processor

See https://github.com/googleapis/repo-automation-bots/blob/main/packages/owl-bot/README.md
