fix: improve type handing of query param parsing

[wesbillman]

When building the requestMap from the supplied query params, we will set the correct type for the given value.

Previously if we received a param like a=10 it would set the type in the request map to string. However, if the field for the request was a []String this would fail the validation step.

We now use the Request data fields to determine how to set the map value.

Basically this:

switch field.Type.(type) {
case *schema.Int, *schema.Float, *schema.String, *schema.Bool:
	queryMap[key] = value[0]
case *schema.Array:
	queryMap[key] = value
default:
	return nil, fmt.Errorf("unsupported type %T for field %q", field.Type, key)
}

Do you want verb.String() here? Won't that be like add(AddRequest) AddResponse type thing?

LOL 🤦 yeah :)
