schedule_on demotes shared_task to task

[invexed]

As the following example demonstrates, cppcoro::shared_tasks become cppcoro::tasks when propagating through cppcoro::schedule_on. Is this intended behaviour?

auto f() -> cppcoro::shared_task<int>
{
    co_return 0;
}

auto tp = cppcoro::static_thread_pool{};
auto g = cppcoro::schedule_on(tp, f()); // g is a cppcoro::task<int&>
