Mention RETURNING ... INTO target

The following documentation comment has been logged on the website:

Page: https://www.postgresql.org/docs/14/sql-insert.html
Description:

It looks like INSERT INTO ... RETURNING allows defining a target for the
returned values like SELECT ... INTO does.

This could be mentioned in the synopsis, or at least in the description of
"output_expression", maybe even garnished with an example.

Thanks,
