generate cannot resolve custom slice type

### What happened?

I used autobind to connect graphql to my custom types. My custom types include a field that is a type with the same underlying slice. However, when I do this, the `graph/schema.resolvers.go` now includes a resolver function for that type.

### What did you expect?

If I change my custom type to use `[]User` instead of `Users` then the custom resolver goes away.

I believe gqlgen should understand that this is the same type and should not require me to implement a custom resolver.

### Minimal graphql.schema and models to reproduce

```graphql
type Todo {
users: [User!]!
}

type User {
id: ID!
name: String!
}

type Query {
todos: [Todo!]!
}
```

```go
package graphql

type Todo struct {
Users Users
}

type Users []User

type User struct {
ID string
Username string
Extra string
}
```

```yaml
autobind:
- "path/to/my/types"
```

### versions
- `go run github.com/99designs/gqlgen version`? v0.17.40
- `go version`? go version go1.21.3 linux/amd64

## Extra Notes

Is this due to the type resolution not checking the underlying type for matches? If so, I am happy to try to implement this. I've started looking through the code but would appreciate pointers for where to look.
