Doc: add missed entries in BRIN extensibility tables.

The tables in "71.3. Extensibility" listing the support functions
for bloom and minmax-multi opclasses should include the associated
options function.  While this isn't quite as required as the rest,
you need it for full functionality of the opclass.

Back-patch to v14 where these functions were added.
