Update 02_build_a_dashboard.rst

Browse Source 
The useService("rpc") function is deprecated in odoo 18.

Now, the default way to call a controller which is not associated with a model is using the rpc function located in the web/static/src/core/network/rpc.js.

Therefore updated the "4. Call the server, add some statistics"  section to reflect the correct references in the odoo 18 tutorials/discover_js_framework docs.

The `awesome_dashboard` addon provides a `/awesome_dashboard/statistics` route that is meant
to return some interesting information.
To call a specific controller, we need to use the :ref:`rpc service <frontend/services/rpc>`.
It only exports a single function that perform the request: :code:`rpc(route, params, settings)`.
To call a specific controller, we need to use the *rpc* function from `@web/core/network/rpc`.
The `rpc` function takes a route as an argument and performs the request: :code:`rpc(route, params, settings)`.
You can also pass `params` and `settings` as *optional* arguments.
A basic request could look like this:
.. code-block:: js
import { rpc } from "@web/core/network/rpc";
...
setup() {
this.rpc = useService("rpc");
onWillStart(async () => {
const result = await this.rpc("/my/controller", {a: 1, b: 2});
const result = await rpc("/my/controller", {a: 1, b: 2});
// ...
});
}
