timezone data: update to 2022g

Update timezone data to 2022g.

* https://mm.icann.org/pipermail/tz-announce/2022-November/000076.html

- In the Mexican state of Chihuahua, the border strip near the US
  will change to agree with nearby US locations on 2022-11-30.
  The strip's western part, represented by Ciudad Juárez, switches
  from -06 all year to -07/-06 with US DST rules, like El Paso, TX.
  The eastern part, represented by Ojinaga, will observe US DST next
  year, like Presidio, TX.
- A new Zone America/Ciudad_Juarez splits from America/Ojinaga.

- Much of Greenland, represented by America/Nuuk, stops observing
  winter time after March 2023, so its daylight saving time becomes
  standard time.
