[ALL] documentation: document calling wizards through XML-RPC

[Yenthe666]

Impacted versions: All

Steps to reproduce: Look at the docs about the XML-RPC (https://www.odoo.com/documentation/13.0/webservices/odoo.html).

Current behavior:
There is no information about how to call wizards and how to set contexts.

Expected behavior:
Documentation sample about calling wizards (with and without context)

@mart-e what do you think? Couldn't find any reference or doc about it :)

Hi,

Calling wizard is like any other models. You call create to have an id and then the specific method you want with this id.
As for context, it is a simple positional argument like you have offset and limit on the search example.
At rpc level, wizard are like any other modules.

cc @Feyensv in case he plans to improve the rpc documentation in the future and make it clear.

I don't think either wizards should be treated in a special way in the documentation. The only difference is about their persistence in DB, but not the way they are handled through ORM/external API.
