upgrade-route-json (U1906)

A route uses type='json', renamed 'jsonrpc' in Odoo 19.0.

Applies to Odoo 19.0 and later.

What it does

Reports type="json" in @http.route(...).

Why is this bad?

Odoo 19.0 renamed the route type jsonrpc; json is a deprecated alias (Odoo’s script 18.1-02-route-jsonrpc).

Fix safety

Safe: the value becomes jsonrpc.
