Coach Review Modal - Rich Text

[mikhael28]

In ApproveExperienceModal, we want to change the coach notes from being a simple form field to being a rich-text field, where the coach can leave detailed feedback instead of simple font. We will then want to update the view on the mentee's side, to review the notes in dangerouslySetInnerHtml or another form to display the rich-text.

We already have quill.js, but I am not super happy with it (250kb in bundle size) - you can implement the same system we have already, but I am also open to other rich text suggestions. Please give an indication of what the bundle size contribution of a new NPM module is!
