Switch to using Runic.jl as code formatter.

Inspired by the short JuliaCon talk, this tests out how Runic would format Manopt and whether the CI would work.

I think the Runic.jl-formatted code looks fine, and Runic might be a more future-proof solution than staying with JuliaFormatter v1 or hoping JuliaFormatter v2 is correct now.

[kellertuer]

Thanks for checking. Yeah I am not sure how far JuliaFormatter v2 is, maybe the only disadvantage of Runic is, that there is a bit of setup compared to JuliaFormatter which works “out-of-the-box” with VS code.

[mateuszbaran]

I actually always run JuliaFormatter from REPL because I wasn't sure the VSCode integration does the right thing, so that's not a problem for me. As long as formatting is one REPL command, I'm fine (I just grab it from REPL history).

[kellertuer]

Nice, I actually did that for most of the time as well, sometimes using the shortcut to format the current file, but hat we also have with runic. And runic also has a bash command that one can easily set up :)

Then we could probably really switch to runic. Nice!
