[9] Move the Network group over to the tox gen script

[sentrivana]

• remove hardcoded entries for requests, grpc from the tox template
• remove them from the ignore list in populate_tox.py
• run populate_tox.py to fill in entries for them
• run split_gh_tox_actions.py to generate the CI yaml files so that they correspond to the new tox.ini

The remaining integrations in this group are not trivial to port to the script, I'll do this step by step in follow-up PRs.

Should we be concerned that tests for 3.8 and 3.11 are gone?

[sentrivana]

Same reply as in the other PRs -- we're shrinking the Latest group by taking stuff out of it. So this is ok. It's all moving into the Pinned group instead.

[szokeasaurusrex]

In the .github/workflows, we don't have either of these Python versions. Is that because the line changed in this PR is for the latest tests?

[sentrivana]

Yes, you have to look at Python versions in the Pinned group instead, that's what gets generated by this script.
