 In [changeset:"54516" 54516]:
 {{{
 #!CommitTicketReference repository="" revision="54516"
 Tests: Replace the timezone used in date/time tests.

 The `Europe/Kiev` timezone has been deprecated in PHP 8.2 and replaced
 with `Europe/Kyiv`.

 The tests updated in this commit are testing the WordPress date/time
 functionality. They are **not** testing whether WP or PHP can handle
 deprecated timezone names correctly.

 To ensure the tests follow the original purpose, the use of `Europe/Kiev`
 within these tests is now replaced with the `Europe/Helsinki` timezone,
 which is within the same timezone as `Europe/Kyiv`. This should ensure
 that these tests run without issue and test what they are supposed to be
 testing on every supported PHP version (unless at some point in the future
 `Europe/Helsinki` would be renamed, but that's a bridge to cross if and
 when).

 Note: Separate tests should/will be added to ensure that relevant
 date/time related functions handle a deprecated timezone correctly, but
 that is not something ''these'' tests are supposed to be testing.

 Follow-up to [45853], [45856], [45876], [45882], [45887], [45908],
 [45914], [46577], [46154], [46580], [46864], [46974], [54207].

 Props jrf, costdev, SergeyBiryukov.
 Merges [54217] to the 5.6 branch.
 See #56468.
