doc: Remove incorrect description about dropping replication slots.

pg_drop_replication_slot() can drop replication slots created on
a different database than the one where it is executed. This behavior
has been in place since PostgreSQL 9.4, when pg_drop_replication_slot()
was introduced.

However, commit ff539d mistakenly added the following incorrect
description in the documentation:

     For logical slots, this must be called when connected to
     the same database the slot was created on.

This commit removes that incorrect statement. A similar mistake was
also present in the documentation for the DROP_REPLICATION_SLOT
command, which has now been corrected as well.

Back-patch to all supported versions.
