docs(kanban): fix worker skill setup instructions too (NousResearch#20960)

Follow-up to NousResearch#20958. The worker skill section had the same stale
'hermes skills install devops/kanban-worker' command — kanban-worker
is also bundled, so that command fails with 'Could not fetch from any
source.'

Replace with bundled-skill verification + restore pattern, matching
the orchestrator section. Uses <your-worker-profile> placeholder since
assignees vary (researcher, writer, ops, linguist, reviewer, etc.)
rather than a single fixed 'worker' profile.

 The dispatcher also auto-passes `--skills kanban-worker` when spawning every worker, so the worker always has the pattern library available even if a profile's default skills config doesn't include it.
