[Core] Handle `TypeError` when `RayTaskError.cause` is a `BaseExceptionGroup`

[Atry]

Why are these changes needed?

TypeError can be raised from __new__ when the cause is a BaseExceptionGroup. Therefore, this PR moves the instantiation into the try block so that TypeError raised from __new__ can be handled.
