Autobind error message is wrong

### What happened?

```graphql
type User {
tags: [String!]!
}
```

```go
type User struct {
tags string
}
```

If I exec gqlgen, I get the following error.

`2023/06/22 03:31:20 String is incompatible with string`

The reason for this is not clear, since `String` and `string` are supposed to be bindable.

### What did you expect?

`2023/06/22 03:31:20 [String!]! is incompatible with string`

It is also more desirable if the corresponding file and line are output.

`2023/06/22 03:31:20 user.graphql:2 [String] is incompatible with string`

### Minimal graphql.schema and models to reproduce

```graphql
type User {
tags: [String!]!
}
```
