Bug description:
  The ICU data we embed in tzdata was out of sync on the 2022f-0ubuntu1
  upload, still matching the 2022e data instead. It's been updated
  upstream, so we need to do another round of SRUs for it:

  The following Python script should work with the update and crash on
  obsolete data:

  from datetime import datetime
  from icu import ICUtzinfo, TimeZone
  tz = ICUtzinfo(TimeZone.createTimeZone("America/Chihuahua"))
  before = datetime(2022, 10, 1)
  after = datetime(2022, 11, 2)
  assert(tz.utcoffset(before) == tz.utcoffset(after))
