[tz] [PROPOSED] Improve Palestine predictions for 2025 and later

[Paul Eggert]

* NEWS: Mention this.
* asia (Palestine): Guess Fri>=23, not lastFri, for fallback
transitions in the future.  Fri>=23 is more consistent with past
practice than lastFri.  The first differing prediction is a
fallback on 2025-10-24, not 2025-10-31.
