p5-DateTime-TimeZone: update to 2.46

2.46    2020-12-22

- This release is based on version 2020e of the Olson database. This release
  includes contemporary changes for Russia (Volograd).

2.45    2020-12-21

- Fixed handling of Etc/GMT[+-]XX zones. Confusingly, the POSIX interpretation
  is that Etc/GMT+1 is 1 hour _behind_ UTC, and Etc/GMT-1 is 1 hour
  ahead. This is the opposite of what this module started doing in the 2.38
  release when it added support for these zones. Reportd by Matthew Horsfall
  (#47). Changes are based on his PR #48.
