break: remove limited updated/delete feature (#3907)

BREAKING CHANGE

As agreed on https://github.com/PostgREST/postgrest/issues/3013#issuecomment-1770186262,
this removes the limited update/delete feature.

The feature was complicated, largely unused and caused other bugs in
mutations.

It was added in #2195 and #2211.
