Delete command doc page is not linked from deleteOne/deleteMany shell helper page

Description

The delete command should be linked from the deleteOne/deleteMany pages with a line similar to the other shell helpers which say "this helper wraps the XXXXXX database command".

The remove shell helper also doesnt have this line, it instead links lower down in the page when talking about write concern. It may be worth standardizing this format deliberately across all shell helper doc pages, as it seems somewhat inconsistent.
