Add name to validation rule in ReadOutResQueryValidator

The validation rule in the `ReadOutResQueryValidator` class was updated to include a `WithName("Identifier")` call. This assigns a name ("Identifier") to the rule, improving the clarity and usability of validation error messages, especially in scenarios where multiple rules are applied and need to be distinguished.
