gqlgen converting the special chars to unicode breaking the frontend

### What happened?
```go
func (r *mutationResolver) OauthRequest(ctx context.Context, typeArg string) (string, error) {
return "http://test.com?name=jane&lastname=doe", nil
}
```
It returns the URL and converts the `&` to Unicode chars. I have frontend app where we return this URL and redirect to the below URL but URL is considered as broken
```
http://test.com?name=jane\u0026lastname=doe
```

### What did you expect?
It should return `http://test.com?name=jane&lastname=doe` so I can redirect the same.

Note: We do not have permission on frontend to add custom code so we are not able to decode this on frontend
