Fix: Correct workflow_path in bmad-quick-flow/quick-spec steps (#1368)

- Fix workflow_path in step-01-understand.md, step-02-investigate.md, and step-03-generate.md
- Changed from non-existent 'create-tech-spec' to correct 'quick-spec'
- Aligns with step-04-review.md which already had correct path
