bug: "gh aw list": should also output number of workflows, similar to "gh aw status"

[bmerkle]

"gh aw list": should also output number of workflows, similar to "gh aw status"

currently, for this new command option, the output of number of workflows is missing.
Please implement this consistent with "gh aw status"

example:

gh aw status
✓ Fetched 1 public and 3 internal workflows
╭───────────────────┬─────────┬──────────┬────────┬────────────────┬────────┬────────────┬────────────────╮
│ Workflow          │ Engine  │ Compiled │ Status │ Time Remaining │ Labels │ Run Status │ Run Conclusion │
├───────────────────┼─────────┼──────────┼────────┼────────────────┼────────┼────────────┼────────────────┤
│ daily-team-status │ copilot │ Yes      │ active │ 30d 16h        │ -      │ -          │ -              │
╰───────────────────┴─────────┴──────────┴────────┴────────────────┴────────┴────────────┴────────────────╯

 gh aw list
╭───────────────────┬─────────┬──────────┬────────╮

├───────────────────┼─────────┼──────────┼────────┤
