chore(ci): temporarily disable link validation workflow

- Add if: false conditions to all jobs to prevent execution
- Add disabled-check job to indicate the workflow is disabled
- Preserves original conditions in comments for easy re-enabling

To re-enable: Remove the 'if: false' conditions and disabled-check job
