Use syntax supported by Nextflow language support

[Jakob37]

Description of feature

As you might have seen, Nextflow has recently introduced a proper language server!

Meaning that developing in Nextflow DSL-2 gives proper editor support with error highlighting, auto-completion, quick navigation through references and so on. A huge difference for the dev experience :D

It can also visualize how processes / workflows connect. Here is the Tomte workflow illustrated by the VSCode plugin (in my Peddy-WIP branch):

Tomte is currently using some syntax not supported by this plugin, such as the switch statement and for loops. Not a lot, I just needed to touch a handful places to get it error free and working.

Would it make sense to adapt the Tomte syntax to align with the syntax expected here?

Good point! The addition of the nextflow language server is so nice and we should try to adhere to the standards. I think that @Lucpen also opened an issue to remove the switch logic from the pipeline, #183.
