* southamerica (Chile): Chile's 2022 start this spring is delayed

Briefly:

Palestine transitions are now Saturdays at 02:00.
Simplify three Ukraine zones into one.
Jordan and Syria switch from +02/+03 with DST to year-round +03.
Changes to future timestamps
+ Fiji will not observe DST in 2022/3. (Thanks to Shalvin Narayan.)
+ For now, assume DST is suspended indefinitely.
+
Palestine now springs forward and falls back at 02:00 on the first
Saturday on or after March 24 and October 24, respectively. This
this means 2022 falls back 10-29 at 02:00, not 10-28 at 01:00.

Mexico’s Chamber of Deputies was supposed to vote today on
legislation abolishing DST in most of Mexico. Although the vote
was delayed due to Internet problems, news coverage of the
non-event led me to review our sources for DST in Mexico, and I
found that tzdb considered the transitions in 1931 to be two
changes to standard time, whereas it is considered to be DST in
today’s news coverage, as well as in our main source, the history
of Mexican local time published by the Investigation and Analysis
Service of the Mexican Library of Congress. Fix this by
considering the 1931 changes to be DST, not standard time.
* NEWS: Mention this.
* northamerica (Mexico): Add DST rules for 1931.
(America/Mexico_City, America/Ojinaga, America/Chihuahua)
(America/Hermosillo, America/Mazatlan, America/Bahia_Banderas):
Use them.

* asia (Palestine): Say "Sat<=30" instead of "Sat>=24".
These have equivalent effect, so this does not change the
generated data. “Sat<=30” is a bit closer to the intended
“Saturday before the last Sunday” given by Heba Hamad.
