doc: Inform about aminsertcleanup optional NULLness
This index AM callback has been introduced in c1ec02be1d79 and it is
optional, currently only being used by BRIN. Optional callbacks are
documented with NULL as possible value in amapi.h and indexam.sgml, but
this callback has missed this part of the description.
