Doc: fix missing/bogus documentation of range_intersect_agg().

The form taking anymultirange had not been documented.  This was
fixed in HEAD in b21c4cf95, but that should have been back-patched
to v14 since the function was added there.  Do so now.

Also, the form taking anyrange was incorrectly documented as
returning anymultirange, when it returns anyrange.

Remove b21c4cf95 from the v15 release notes, since it no longer
qualifies as new-in-v15.
