Document pre-commit version synchronization with con-pca-tasks

Summary

Added documentation comments to .pre-commit-config.yaml indicating that pre-commit hook versions are synchronized with the DHS-CISA-con-pca-tasks repository for consistency across CISA repositories.

This is part of a cross-repository maintenance effort to keep pre-commit hook tooling consistent between DHS-CISA-XFD and DHS-CISA-con-pca-tasks. A corresponding PR in con-pca-tasks ([link to be added]) updates that repository's pre-commit hooks to match the versions already present in this repository.

Changes:

• Added 2 comment lines at the top of .pre-commit-config.yaml documenting the synchronization policy

Review & Testing Checklist for Human

• Verify this documentation aligns with the team's actual maintenance strategy for these repositories
• Confirm the comment placement and wording are appropriate

Notes

• This is a documentation-only change with no functional impact
• Corresponding PR in DHS-CISA-con-pca-tasks updates 12 pre-commit hook versions to match this repository
• Part of cross-repository maintenance demo
