pg_resetwal: Update an obsolete comment

petere · petere · commit 7273945cafa7 · 2023-09-28T11:27:22.000+02:00
The comment claimed that pg_resetwal updates the pg_control file if it is of an old version. This has apparently never been true. Also, in c3c09be, another comment was added elsewhere that this currently does not happen. So this comment is wrong and redundant and can be removed.
