QA:

❌ run -h and --help on all project commands, make sure the --target-org flag summary has been updated.
- These commands now have no summary at all; the rest look good:
- project deploy cancel
- project deploy quick
- project deploy report

Second QA after fixes:

✅ run -h and --help on all project commands, make sure the --target-org flag summary has been updated.
