Bug description:
  [ Impact ]

  The 2025a release contains the following changes:

  * Paraguay adopts permanent -03 starting spring 2024
  * No leap second on 2025-06-30

  [ Test Plan ]

  Test cases were added to the autopkgtest to cover the testing:

  * python: test_2025a
  * python-icu: test_2025a (only for focal and newer)

  So the test plan is to check that the autopkgtest succeeds.

  [ Other Info ]

  The autopkgtest for chrony is flaky on jammy and newer (see bug
  #2002910).

  This tzdata release causes the postgresql autopkgtest to regress (see
  bug #2098518)
