Update GitHub Actions Version

Update action versions in GitHub Actions workflow files, focusing on major version changes only.

Important Principles: Explanation of GitHub Actions Version Tagging System

• Using a major version number (e.g., v4) automatically fetches the latest minor and patch versions.
• For example, actions/checkout@v4 will automatically get versions like v4.2.2, v4.3.0.
• Do not update from v4 to a specific version like v4.2.2 — this is unnecessary.
• Only update when the major version changes (e.g., from v5 to v6).

Note: Skip fatjyc/update-submodule-action@v6.0 updates as the new version is broken.

Steps

0. Find Workflow Files

Look for files in .github/workflows/ recursively. Note that composite actions may be used — read both the composite action and the calling workflow simultaneously.
