`@can` directive throws error for basic gate ability

[6XGate]

Describe the bug

When running a query or mutation that does not return an Eloquent model with a basic gate ability for the @can directive, it throws a DefinitionException stating Failed to find class ${graphQlType} in namespaces [...${modelNamspaces}] for directive @can..

Expected behavior/Solution

It should not fail without a model, but rather fallback to using any gates defined with Gate::define or similar methods.

Steps to reproduce

1. Create a mutation or query using a custom resolver. That resolver should not return an Eloquent model.
2. Define a basic gate in app/Providers/AuthServiceProvider.php using Gate::define. For example, it could be called read.
3. Add a @can(ability: 'read') directive to the operation in step 1.
4. Call the operation from a client.

@can deals with policies, not gates. Feel free to reformulate this issue as a feature request, I am open to pull requests.
