Fix CoreBridgeCallTimeoutTestCase's byteman rule file for proper method match at runtime

In JDK 19 EA 22 new Virtual Threads feature have been introduced in JDK.
This new feature introduced another Thread.sleep() method with Duration parameter.
So there are two similar methods now:

Thread.sleep(long)
Thread.sleep(Duration)

Because Byteman script provided value represents integer, Byteman runtime
is unable to decide which one of these two methods to use.
To ensure proper method selection, we need to ensure btm Thread.sleep() method
value represents long and not int.
