check_po_files uses the format defined in

<lang>/messages/ki18n/ki18n{5,6}.po for ki18n translations;
<lang>/messages/ki18n/kcoreaddons{5,6}_qt.po for Qt translations.

https://invent.kde.org/sysadmin/l10n-scripty/-/blob/master/check_po_files#L38
We did this because in some cases the definitions we use differs a bit from
the ones defines elsewhere (especially plural forms), so it was decided to use
some of our "base" files as reference.

It seems that the older German translation files, including ki18n5.po and
ki18n6.po, uses the form without parentheses.
So you may want to run a global search-and-replace and set all German files to
use the form with parentheses. If you do that, the next run of check_po_files
shouldn't try to remove them anymore (I hope).
