Subject: [PATCH] fix(Utils): Inherit from `Ts` in `OverloadSet` Signed-off-by:
 erick-alcachofa <erick@artichoke.dev>

This commit changes the `OverloadSet` utility class to publicly inherit
from its template parameters `Ts...`. This allows the `operator()` from
each provided type to be brought into the overload set, efectively
fixing it's functionality that would be broken otherwise.

It also includes the missing `<ranges>` header in the test utilities.
