Adds language support to ckeditor5.
A few disclaimers:
- This only works in upload/elfinder mode (see below screenshots in "base64" mode)
- The way I copy-pasted the editor config is not ideal
- It's not perfect because it does not support pt_BR, sr-latin and zn-cn, but that can be fixed later.
Here is what it looks like in elfinder mode:
Oddly in base64 mode it looks like gibberish:
CkEditor has its own way of handling translation and I'm not sure if it's because the JS translation files were generated in a certain way and maybe need recompiling.
