Remove pids from operator runcard

[alecandido]

Ok, might be weird, but it is not wrong. This is a problem with the runcard: if you do not want pids to be in the OperatorCard, please open a separate PR based on this one.
I would say that it should be easier to fix, but it might propagate in a few places. Since it is weird but not completely wrong (most of the time you just use the example one, that has the correct basis), then I'd rather not consider blocking for this PR.

Can you open the further PR yourself? @felixhekhorn

Yes, it seems like I forgot to link to the PR, and forgot to close after merging :)
