Add new language in editor

[NilsJacobsen]

Hey folks,

What do you think about adding new languages in the editor UI.
I think it could really help if you are a contributor and just want to add for example your native language.

That would add a new json file that is basically empty and can be filled with with the UI in the editor.
Do you think this would be a big step?

FYI
I saw that listmonk is explaining how to contribute in their old editor in the docs and I saw that this was possible.
