Bug description:
  [ Impact ]

  I install latest updates on my Ubuntu 20.04 and 22.04 and timezone has changed from Europe/Kiev to Europe/Kyiv, which caused error in my service:
  pytz.exceptions.UnknownTimeZoneError: 'Europe/Kyiv'

  The problem exists on:
  Ubuntu 20.04 python3-tz version - 2019.3-1
  Ubuntu 22.04 with version of python3-tz - 2022.1-1.
  The problem is solved for kinetic release. Could you please add 'Europe/Kyiv' timezone for previous releases.

  [ Test plan ]

  Execute following script:

  ```
  #!/usr/bin/python3
  from pytz import timezone
  print(timezone('Europe/Kyiv'))
  ```

  [ Where problems could occur ]

  The list of timezones are brought up-to-date with the latest tzdata
  version, but this can cause failures with outdated tzdata package
  versions.
