Tentative release schedule for Emacs 29.1

[Lars Ingebrigtsen]

Eli and I have discussed the schedule, and we've decided to
(tentatively) aim for cutting the emacs-29 branch in two months time;
i.e., late November.  After that, we'll be doing pre-releases from that
branch, and then as usual -- bug fixes on the emacs-29 branch and new
features on "master", and then the Emacs 29.1 release sometime in
spring.

So if anybody have some new features they really want to have in Emacs
29.1, they should push them to "master" soonish.
