feat(workflow): update commit timestamp for patching
Add a step to set the commit timestamp of the HEAD commit to be 1
second newer than the oldest of the last 3 commits. This ensures
proper chronological order while preserving the commit content.
- Fetch deeper history to access commit history
- Get oldest timestamp from recent commits
- Set new commit date with BSD-compatible date command
- Verify timestamp change with git log
The workflow was previously checking out 'main' branch with a
comment indicating it needed to be fixed. This change makes it
properly checkout the tag specified by the workflow input.
