ci: Fix commit and push in regenerate models workflow (#702)

## Summary

Fixes two bugs in the `manual_regenerate_models` workflow that caused
the [manual
run](https://github.com/apify/apify-client-python/actions/runs/24075156216/job/70221653926)
to fail:

- **Pre-commit hook blocked commit**: `git commit` triggered the
type-check hook, which failed because regenerated models removed symbols
(`ScheduleCreateActions`, `TaskOptions`) still imported by client code.
Added `commit: --no-verify` to bypass hooks — the resulting PR will get
proper CI checks anyway.
  - pre commit failures should be addressed manually
- **Push failed for new branch**: `push: --force` ran `git push --force`
without setting upstream tracking. Changed to `push: -u origin $BRANCH
--force` so the new branch is correctly pushed.
