@nf-core-bot fix linting

[mirpedrol]

Hi @bjlang are the tests on this PR finished? Or is it still WIP? We are thinking on merging it for the next release (which will hopefully happen during next week)

[bjlang]

@mirpedrol tests were finished. But I assume that more of this will become invalid/irrelevant with the move to components

[mashehu]

tests were finished.

Finished as you wrote them? Because I can't see them in the PR.

But I assume that more of this will become invalid/irrelevant with the move to components

Partially, but this is a very good starting point for the move. 🙂
