Challenge: Flexible Type Validation Decorator

Завдання

Create a flexible decorator for validating data types:

Define the validate decorator, which should take data types (str, int, bool, etc.) as arguments and annotate them using the type keyword.
Define the inner function that takes a function (func) as an argument.
Define the wrapper function that takes *args.
Check if each argument is an instance of one of the specified types.
Functions should return:

The wrapper() should return the result of func() with the provided arguments.
The inner() should return wrapper without calling it.
The validate() should return inner() without calling it.

Validate the snake_string() function for the str data type using the @validate decorator.
Validate the multiply() function for the int or float data types using the @validate decorator.
