Morph relations are not working.

Morph relations create 2 columns in the db tables:

For example, if you create a test morph relation:

class Example extends Model
{
    protected $guarded = [];

    public function testable(): MorphTo
    {
        return $this->morphTo();
    }
}

public function up(): void
{
    Schema::create('examples', function (Blueprint $table) {
        $table->id();
        $table->morphs('testable');
    });
}

This will result in 2 columns in the examples table:

• testable_id (id of the related model)
• testable_type (fqcn of the related model)

And in the Swagger documentation we can see 2 fields:

• testable => OK with this PR, it will work as expected if we submit an IRI
• testable_type => this field is useless and should not be displayed?

testable_type => this field is useless and should not be displayed?

You can hide that field within:

Thanks for the patch, it'd be lovely if you could add a test (there are many examples in the workbench directory.
