@resolve produces incorrect query in fusion graph when the field name differs from the query name

Describe the bug

I have a subgraph "A" that has a query widgetById(widgetId: ID!): Widget! and another subgraph "B" that has a type with a widgetId field type Thing { widgetId: ID! }. I want to extend this type with a field widgetName that is resolved from the Widget.name field.

I added this to schema.extensions.graphql in subgraph "A"

extend type Thing
{
    widgetName(widgetId: ID! @require(field: "widgetId")): String @resolve(select: "widgetById(widgetId: $widgetId) { name }")
}

which produces this in the fusion graph:

  widgetName: String
    @source(subgraph: "SubgraphA")
    @variable(subgraph: "SubgraphB", name: "Thing_widgetId", select: "widgetId")
    @resolver(subgraph: "SubgraphA", select: "{ widgetName(widgetId: $Thing_widgetId) }", arguments: [ { name: "Thing_widgetId", type: "ID!" } ])

and when I try to query that field, I get an error:

    {
      "message": "The field `widgetName` does not exist on the type `Query`.",
      "locations": [
        {
          "line": 1,
          "column": 46
        }
      ],
      "extensions": {
        "type": "Query",
        "field": "widgetName",
        "responseName": "widgetName",
        "specifiedBy": "http://spec.graphql.org/October2021/#sec-Field-Selections-on-Objects-Interfaces-and-Unions-Types"
      }
    }

I would expect the fusion graph to produce the query that I'm passing into the @resolve directive.

resolve is not yet supported..... so no bug here.

Alright. What is the proper way to do what I'm attempting then? There's no documentation for fusion so I'm fumbling around in the dark here.

Will this PR add the proper features to do what I'm trying to do here?
