ci: 🤖 Update test matrix with new releases (09/21)

[github-actions]

Update our test matrix with new releases of integrated frameworks and libraries.

How it works

• Scan PyPI for all supported releases of all frameworks we have a dedicated test suite for.
• Pick a representative sample of releases to run our test suite against. We always test the latest and oldest supported version.
• Update tox.ini with the new releases.

Action required

• If CI passes on this PR, it's safe to approve and merge. It means our integrations can handle new versions of frameworks that got pulled in.
• If CI doesn't pass on this PR, this points to an incompatibility of either our integration or our test setup with a new version of a framework.
  • Check what the failures look like and either fix them, or update the test config and rerun scripts/generate-test-files.sh. See scripts/populate_tox/README.md for what configuration options are available.
