Fund: ow.create does not return an Assertion Functions type / `asserts` annotation is missing

Currently, ow() funciton is of type Assertion Functions.

Lines 31 to 46 in f26115d

           	<T>(value: unknown, predicate: BasePredicate<T>): asserts value is T;

           	*/ 
        
           	<T>(value: unknown, label: string, predicate: BasePredicate<T>): asserts value is T;

However, the ReusableValidator returned by ow.create() is not an Assertion Functions type.
ReusableValidator returns a void type!
In addition, the value argument does not seem to be of type unknown...

           	@param label - Override the label which should be used in error messages.

           	// eslint-disable-next-line @typescript-eslint/prefer-function-type 
        
           	(value: T, label?: string): void;

For this reason, using ow.create() in TypeScript does not provide proper type validation.
