linting tests for quotes in versions command

[maxulysse]

Description of feature

both quotes or non quotes are working with linting, so we are already not consistent on that decision.
Given the fact that we might want to use quotes to preserve some characters, and that consistency is my hill to die on, I would rather we force this usage.

@nvnieuwk agreed with me

I feel like I don't want to ever care about this level of consistency personally. If anything, it should be handled by automatic formatters like Prettier etc.

the inconsistencies are probably because we switched the parsing a bit.
The main problem is that we don't enforce the nextflow code for single or double quote and it is too much of a PITA to handle all weird cases imo.
Unfortunately prettier doesn't seem to have any opinion about quotes there.
Because these key names should be autogenerated, we shouldn't care too much.
