@requires directive breaks code generation when @entityResolver is used

[chedom]

What happened?

@requires directive breaks code generation when @entityResolver is used.
Geneation brakes with an error:

federation: federation.gotpl: template: federation.gotpl:160:18: executing "federation.gotpl" at <.Fields>: can't evaluate field Fields in type *federation.Requires

What did you expect?

Resolvers should be generated.

Minimal graphql.schema and models to reproduce:

1. Go to plugin/federation
2. Add next type to testdata/entityresolver/schema.graphql

type MultiHelloRequires @key(fields: "name") @entityResolver(multi: true) {
    name: String! @external
    key1: String! @external
    key2: String! @requires(fields: "key1")
}

3. Run the command go generate

Got: federation: federation.gotpl: template: federation.gotpl:160:18: executing "federation.gotpl" at <.Fields>: can't evaluate field Fields in type *federation.Requires
Expected: no error
