Timezone Europe/Berlin does not have DST transitions about core

Most probably related to php/php-src@091c092, which is a huge diff (52,924 additions and 29,617 deletions).

I've opened a PHP bug: https://bugs.php.net/bug.php?id=80963

Quoting from the bug:

This is a tricky one. The data format that the library uses has changed, and will now only contain a list of transitions up until the last time the rules changed.

For America/New_York, that was in 2007, and Europe/London, in 1996

The tests in question have been disabled for the time being by only running them with PHP up until 8.1.0-dev:

https://bugs.php.net/bug.php?id=80963 was closed on August 8th, retesting with current PHP verifies this once again works as expected.
