✨Endpoint to create a doc from a string.

[AntoLC]

Feature Request

We want to interconnect Meet with Docs, Meet has a string and want to create a doc with it.
Problem, to fit the system the content has to be a Y.Doc with a json formatted in a way to be readable by the frontend editor.

Possible solution

Adapt POST /api/v1.0/documents/ to convert automatically in the good format depend some param.
By example, if create_content is set during the POST we will convert to Y.doc by ourself on the backend side:

Request payload:
{
   create_content: string;
   title: string;
}
