Improved formatting for ListLiterals in multi dimensional lists

[eyn9xwy]

This PR fixes an issue with the layout of list literals by using a new line when a threshold of three elements per list is exeeded.

Not sure what others think about it, but sometimes it feels like there are too many line breaks after this change and I am not sure if this helps with readability. Another option would be to only use breaks when the list literal contains a certain number of elements e.g. 3 or 5 or rather create a new concept for those matrix-style initialisations.

Fair point, but in our case the lists may look something like this:

There's no apparent structure, so I don't think a static rule like "line break after n elements" will do the trick.
I'll talk to my team about creating a new concept.

Hi @alexanderpann, we have implemented your suggested solution with a static list length of 3 before a line break is enforced. Feel free to have a look at the examples provided. Thanks!

[alexanderpann]

I am fine with this change.

Hi @alexanderpann would you kindly have a look at the check that hasn't run successfully yet?

@arimer Can you check why it is not building?

TeamCity is configured to request approval for builds of PRs from forks (for security reasons). I triggered a build.

[sergej-koscejev]

@eyn9xwy the build failed because of some resolveInfo not being up-to-date. Run ./gradlew remigrate locally to fix this.

[arimer]

Line break after a fixed lenght of 3 looks fine. Could you please update the Changelog before we can merge?

[eyn9xwy]

@arimer Done, thank you!
