[7] Move the AI group over to the tox gen script

[sentrivana]

• remove hardcoded entries for huggingface_hub 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. This group in particular needs special treatment because of the notiktoken versions of some of the integrations.
