chore(ci): pin actions in PR-triggered workflows (#3194)

## What changed
- Pinned external GitHub Actions to full commit SHAs in PR-triggered
workflows:
  - `.github/workflows/check-md-link.yml`
  - `.github/workflows/codeql.yml`
  - `.github/workflows/license_check.yml`
  - `.github/workflows/python-ci-docs.yml`
  - `.github/workflows/python-ci.yml`

## Why
- Fixes `zizmor` `unpinned-uses` findings by replacing mutable refs with
immutable SHAs.
- Reduces supply-chain risk from tag/branch drift while preserving
workflow behavior.

## Verification
- `uvx --from zizmor zizmor --offline .github/workflows/ --fix=all`
- Result: `No findings to report.`
