Create-page feature can create either a child or a sibling page -- consider name and doc updates #1647
Description
The create child page feature used to be broken (#668), but was fixed via #1644. This feature will create a child page only when selected from an index page. Otherwise, it creates a sibling page.
I'd suggest that:
- The feature be renamed simply to "Create page" (maybe with a more complete title "Create child or sibling page" ... but that might not be worth it)
- The Repository Links docs be updated to more clearly explain the behavior.
