[Bug] WYSIWYG Editor missing br newline

In the previous editors it was possible to add a simple newline (br tag) by pressing the shift key.
The quill editor always adds a new paragraph. That breaks a lot Layouts of our customers

Maybe this could be a solution: slab/quill#4248 (comment)

@brusch I think this PR solves our problem. Should we wait until this is merged? slab/quill#4565

[brusch]

@robertSt7 yep, makes sense to wait until native support was added 👍
