Clarify the license for the emoji JSON file hosted on the CDN

What is the purpose and what should be changed?

The new emoji plugin pulls emoji definitions from the ckeditor CDN by default. The URL to use when fetching emoji definitions is configurable, so the JSON file could be hosted elsewhere.

Is there a license on the en.json file hosted on the CDN that indicates how it can be used? I don't see the file itself in the ckeditor5 repo in github.

Apologies for the late response!

This file is part of CKEditor 5 distribution and should be treated as such. You can find the licensing information in https://github.com/ckeditor/ckeditor5/blob/master/LICENSE.md

Ah, and the license also notes that emojibase-data is included under the MIT license:
emojibase-data - Copyright (c) 2017-2019 Miles Johnson.

The file we host was built for CKEditor 5 purposes (using this dependency), and therefore we recommend thinking about it as about any other dependencies of CKEditor 5 which are integral parts of its distribution.
