Run JuliaFormatter on more files, remove trailing whitespace

[mhauru]

The only actual change is the change in .JuliaFormatter.toml. Everything else is a consequence of running autoformatting and auto-whitespace-removal.

This will clean-up the diff in #1887 a lot, since the formatter has already been run there.

LGTM. I don't entirely feel comfortable with model functions being edited to include return statements (they aren't really functions), but that's probably just me.

[mhauru]

The two syntaxes, with and without explicit return, are equivalent though, and different from having e.g. return nothing, because generated_quantities (and I think @submodel, which will soon be the same thing: TuringLang/DynamicPPL.jl#696) makes use of the return value.

They are equivalent, yeah. I just think that the rationale for inserting return is more applicable to ordinary functions (i.e. be explicit about what you're returning) than it is to models (where the return value isn't always used); but as I said that's just me :)
