As an editor I want to be informed about the license of contributions I am making to EntitySchemas.
**Problem:**
We currently don't show a "license of contributions" message when EntitySchema text is edited like we do when an EntitySchema is created (e.g. https://www.wikidata.org/w/index.php?title=EntitySchema:E123&action=edit).
We need to have the same message appear when EntitySchema text is edited to notify the users.

**BDD**
GIVEN an EntitySchema
AND "license of the contributions" message
WHEN an EntitySchema text is edited
THEN the "license of contributions" message is displayed
**Acceptance criteria:**
[ ] "license of contributions" message is displayed on EntitySchemas when an edit of EntitySchema text is made
