[Bug 1998321] Re: tzdata 2022g release

[Benjamin Drung]

** Description changed:

  The 2022g release contains the following changes:
  
  * The northern edge of Chihuahua changes to US timekeeping.
  * Much of Greenland stops changing clocks after March 2023.
  * Fix some pre-1996 timestamps in northern Canada.
  * C89 is now deprecated; please use C99 or later.
  * Portability fixes for AIX, libintl, MS-Windows, musl, z/OS
  * In C code, use more C23 features if available.
  * C23 timegm now supported by default
  * Fixes for unlikely integer overflows
  
  Changes to future timestamps:
  
  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.  (Thanks to Heitor David Pinto.) 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.  (Thanks to Jonas Nyrup and Jürgen Appel.)

+ CLDR: https://unicode-org.atlassian.net/browse/CLDR-16181
