Replace my implementation of StronglyTypedId to andrewlock's implementation

It would be better to use andrewlock/StronglyTypedId to simplify the code.

After some testing, I decided not to use this package because see no purpose in it. I still have to create a struct for it, moreover, I don't want to use any other dependencies, like Newtonsoft.Json or EfCoreConvertes in the domain project.

public readonly record struct ProductId(Guid Value)
{
    public static ProductId New => new(Guid.NewGuid());
}
