How to skip gqlgen to generate resolver for specific field

### What happened?
I wanted gqlgen to skip creating a resolver for a specific field, in this case, to skip creating a resolver for the "permissions" field. Can gqlgen accomplish this?

```
type Role {
id: UUID!
name: String!
displayName: String!
description: String
permissions: [RolePermissions]
createdAt: Time!
updatedAt: Time!
}

type RolePermissions {
id: UUID!
parentId: UUID
name: String!
displayName: String!
children: [RolePermissions]!
createdAt: Time!
updatedAt: Time!
}
```

I added "resolver: false" to the gqlgen.yml configuration file, but it didn't work as expected. This feature seems to only force gqlgen to generate a resolver, not skip it.

```
Role:
model: models.Role
fields:
permissions:
resolver: false
```

### What did you expect?
When I ran the generate command, I expected gqlgen to skip creating the following resolver:

```
// Permissions is the resolver for the permissions field.
func (r *roleResolver) Permissions(ctx context.Context, obj *models.Role) ([]*graphqlModels.RolePermissions, error) {
panic(fmt.Errorf("not implemented: Permissions - permissions"))
}
```
