Fix quoting and undercore unused variables

[dialvarezs]

When I was looking at the code, I noticed some incorrectly placed quotes and corrected them. Additionally, I prefixed unused variables in this file with _ to suppress warnings reported by the language server.

This one I can do from my phone :D

LGTM and definitely good to start doing the clean up of the code to make linting happy.

I was actually wondering if just before release we do one last PR (which I want to cut when your other big PR is in), of just fixes to make the language server and nf-core linting happy (we have a lot of warnings, particularly in the local modules). Do you think that would be worth it?

But for now this can be merged once you've added yourself to the contributors list on the README!

Sure, I don't like seeing red things in the editor hahaha. I can give it a shot.
