Provide Request instance in on_skipped_request callback #2007

SkippedRequestCallback receives only the URL string, so handlers can't access request metadata (notably user_data) for skipped requests:

SkippedRequestCallback = Callable[[str, SkippedReason], Awaitable[None]]

#1999 implements passing the Request in a backward-compatible way, but that requires dual-dispatching on the callback's parameter type annotation, which is fragile runtime inspection (see this comment). Since v2 allows breaking changes, do it there with a clean signature instead:

SkippedRequestCallback = Callable[[Request, SkippedReason], Awaitable[None]]
