ci(security): resolve security alerts (#12466)

Scorecard has some security alerts that need to be addressed.

- Pinned git commit hashes for scripts sourced from GitHub repositories
in `mk/dependencies/*.sh` scripts.
- Pinned hashes for some GitHub Actions.
- Added comments to cron schedules for CodeQL and Scorecard GitHub
Actions.
- Removed unnecessary `contents: read` permission in the CodeQL GitHub
Action.
