Also requires switching to using `pip_parse` and providing a fully
resolved requirements lock file. This moves the input requirements to
the `requirements.in` file, and processes it with:
```console
$ bazel run //github_tools:requirements.update
```
This will regenerate the `requirements.txt` file that is checked into
the repository. The advice in the documentation is specifically to keep
this file checked into the repository for hermetic builds with stable
Python dependency versions.
This should fix builds on systems where the Python version is 3.12 and
newer and the older version of `rules_python` stops working with errors
due to removal of long-deprecated interfaces.
