could you run please with [full-ci] to make sure everything's in order.

it's a good idea to remove the extras from drone.star

with full-ci we only get extra e2e-tests-multi-service pipeline. This should be unaffected by these changes.
SO I would like to merge this because we need this for ocis bump in reva (which was on hold for a long): cs3org/reva#4957

Suggested change

this is not required. just a leftover code. But we might want to decide to clean or completely remove these files (see #10530)
