docs: add calendar for 23.3

Normally the branchpoint would have been on Oct 11, but this is the week
before XDC and everyone will be busy so let's try not to add the
branchpoint pressure on top. Let's instead branch off on the week
_after_ XDC, on Oct 25.

Besides, 23.2 has been delayed by multiple factors, so it wouldn't make
sense to rush 23.3.
