feat(docs): improve manual setup instructions for workflows

The `gemini-dispatch.yml` workflow is designed to call other workflows
like `gemini-review.yml`, `gemini-triage.yml`, and `gemini-invoke.yml`.

When a user manually sets up only one of these workflows (e.g., only
for PR reviews), they might not have the other workflow files present
in their repository. This can lead to errors when the dispatch
workflow tries to call a non-existent workflow.

This change adds a note to the setup instructions for each of the main
workflows (`pr-review`, `issue-triage`, `gemini-assistant`) advising
users to comment out the unused jobs in their copy of
`gemini-dispatch.yml`.

This prevents errors and makes the manual setup process more robust.

Fixes #256

 You can customize the prompts and settings in the workflow files to suit your specific needs. For example, you can change the triage logic, the labels that are applied, or the schedule of the scheduled triage.
