Allow assertThrows to handle any Throwable (including AssertionsError

[zentox]

Currently, the assertThrows method is constrained to handle only instances of Exception. This limits its ability to catch Throwable instances such as AssertionsError, which is an Error and not an Exception.

Proposed Change:

Update the generic type signature of assertThrows from:

public static <T extends Exception> T assertThrows(Class<T> expected, Callable callable, Context context, PreCommentSupplier<? super ResultOfExceptionalCall<T>> preCommentSupplier)

to

public static <T extends Throwable> T assertThrows(Class<T> expected, Callable callable, Context context, PreCommentSupplier<? super ResultOfExceptionalCall<T>> preCommentSupplier)

The change ensures that assertThrows can handle all types of Throwable, including both Exception and Error types (e.g., AssertionsError).
This also makes the method more flexible and robust, allowing for broader use cases where errors may be thrown during assertions.
