Update content scope scripts workflow description (#6387)

Task/Issue URL:
https://app.asana.com/1/137249556945/project/488551667048375/task/1210785772751175?focus=true

### Description

This PR enhances the automated content scope scripts update workflow by:

1. Clarifying when tests need to run:
- Tests will only run if the
`node_modules/@duckduckgo/content-scope-scripts` folder content has
changed
   - If only the package version changed, tests don't need to run

2. Adding clearer PR checklist with two scenarios:
- When content-scope-scripts folder is updated: all tests and privacy
tests must pass
- When only the package version is updated: all tests must pass but
privacy tests can be skipped

3. Updating the Asana task description to include the same clarification
about when tests need to run
