Fix JuliaFormatter to 1.0.34

[mortenpi]

This downgrades and fixes JuliaFormatter to 1.0.34. I believe this should get rid of the formatting changes in #637. 1.0.34 was the latest JuliaFormatter version when the last API update was merged in #636. My suggestion is to get #637 in with the old formatting, and then figure out how to re-format the generated code.

Note: 1.0.34 doesn't seem to cause any formatting changes on master, so in that sense should be safe to merge.

1.0.56 (what I get when I just ]add JuliaFormatter) also doesn't seem to produce any changes though 😕

On master it doesn't, because they have already been formatted into to function foo(); ...; end form, and it doesn't format them back. But if you re-generate the APIs (which generates the foo() = ... form), then you should see a difference -- 1.0.56 sticks with foo() = ..., but 1.0.34 formats to function foo(); ...; end.

Oh I see, thanks. What you have here seems like a reasonable solution then.

I guess #637 should also update shortly, but FWIW, running locally, this is what the diff should look like with the old formatter: https://github.com/JuliaCloud/AWS.jl/compare/master...mortenpi:AWS.jl:mp/api-diff -- the non-substantial changes seem to be gone.

That's great! Thanks for this
