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!]!
}
```

### versions
- `go run github.com/99designs/gqlgen version`? v0.17.28
- `go version`? 1.20

The error message is generated in the code generation or validation logic. Look for where type incompatibility errors are formatted, likely in a package like 'codegen' or 'validation'. The issue shows the current output 'String is incompatible with string' but expects '[String!]! is incompatible with string' with file and line. Start by finding the function that prints this error, then trace how it resolves types. Check test files for error messages to understand the expected format.
