Remove the accidental 'def' in main.nf Channel initialization

[jessicarowell]

Description

I had accidentally created a function (line 60 of main.nf), which caused a scoping conflict as Nextflow interpreted that I was redefining Channel. Removing 'def' fixes this issue. I'm not sure why it never caused an issue on my system, but that meant I didn't catch it.

def dummy_wait = Channel.value(true) -> dummy_wait = Channel.value(true)
