bug#42917: 27.1; temporary note included in 27 NEWS

[Alex Branham]

Hi all -

The following note:

Temporary note:
+++ indicates that all relevant manuals in doc/ have been updated.
--- means no change in the manuals is needed.
When you add a new item, use the appropriate mark if you are sure it
applies, and please also update docstrings as needed.

is included in Emacs 27.1 NEWS. Judging from previous releases, it
should have been removed, correct?

Thanks!
