[cleanup] Misc (#16452)

* Include `pin*` extras in lockfile
* Fix and clean up `devscripts/update_requirements.py`
* Improve release channel documentation
* Remove false statement from `--prefer-insecure` documentation
* Assorted code cleanup
* Set `GH_TELEMETRY=false` in CI/CD whenever `gh` is used
* Add comments about required checks in CI workflows
* Run `test-workflows.yml` for every PR so its checks can be required
* Verify actionlint attestation in CI
* Remove zizmor version to reduce workflow maintenance burden
