Add changelog entry for last commits.

debian-edu-config (2.10.53) UNRELEASED; urgency=medium

  * Some amendments.

    - debian/debian-edu-config.postinst: Don't run the cert tool inside d-i; the

      installation will break because requisites are not yet ready.

    - share/debian-edu-config/tools/install-task-pkgs: Drop superfluous last

      apt call; the task-desktop package gets already installed before.

    - share/debian-edu-config/tools/improve-desktop-l10n: Fix special case en;

      thunderbird-l10n-en-gb exists, but thunderbird-l10n-en doesn't.
