Toxgen false-positive change detected

[alexander-alderman-webb]

When we added the litellm integration we generated tox.ini since a new test suite was added. The relevant commit is a8156f5.

Subsequent PRs later in the day failed CI because grpc-v1.76.0rc1 is added to tox.ini, and populate_tox.py detects an inconsistency. See https://github.com/getsentry/sentry-python/actions/runs/18221553077/job/51882480538?pr=4883 as an example.

I added a print statement to populate_tox.py that shows that grpc version v1.76.0rc1 was uploaded at "2025-10-03 08:16:42.412198+00:00". The time is a few hours before a8156f5.

My suspicion is that there is some caching in a CDN or the PyPI release system.

As a workaround for now, running scripts/generate-test-files.sh on the PR branch and committing the result should get rid of the failing check.

I think this might have to do with us taking the time of the last commit touching tox.ini to regenerate it -- it's not always correct (could just be the timestamp of toxgen-unrelated changes, or even the timestamp of the merge commit). I'll take a look.
