status: 2023q1: corrections

A commit for the introduction to the status report lacked a word that
was added in Phabricator.

https://github.com/freebsd/freebsd-doc/pull/156
(PR 156) for the Cluster Administrator Team report was mistakenly closed
by me, without committing the report-related changes. Redo the missing
changes (as PR 179).
