HEADS UP: doc/ slush begins for 13.2-RELEASE

Hello,

As announced, the doc tree is now in a slush.  Please postpone all
non-essential changes until after the doc tree is tagged (currently
scheduled for 24 February, 2023).

Please note that the slush does not apply to website/ documents.

While this is not a real freeze, if you need to commit a relatively
large change to fix or improve our documentation for 13.2-RELEASE,
please put a note for translators onto your commit log.
