* import { assertNotInstanceOf } from "@std/assert";
*
* assertNotInstanceOf(new Date(), Number); // Doesn't throw
* assertNotInstanceOf(new Date(), Date); // Throws
* ```

* @typeParam A The type of the object to check.
* @typeParam T The type of the class to check against.
* @param actual The object to check.
* @param unexpectedType The class constructor to check against.
* @param msg The optional message to display if the assertion fails.
