Fix minor YAML mistake

Oops, I didn't understand the different multiline string formats in YAML! I was using one that chomped through newlines, and converted them to normal spaces.

I think that didn't matter in this context anyway? because indentation is an exception to this behavior. What a weird behavior!

Anyway, uhh, yeah, I'll use the simpler multiline string format now 😅 for consistency and clarity!
