doc: Clarify some terms for pg_createsubscriber

The last section of pg_createsubscriber used the terms
"publication-name", "replication-slot-name", and "subscription-name".
These terms are not defined on the page, which was confusing, and the
intention is clearly to refer to the values one would give to the
options --publication, --subscription and --replication-slot. Let's
simplify the documentation by mentioning the option switches, instead of
these terms.
