fix(types): change the type guard on isCancel (#5595)

* fix(types): change the type guard on isCancel

… to `CanceledError<any>`. This makes more sense as it reflects what
`isCancel` is actually doing. In fact, if I'm not mistaken, the
`Cancel` type is no longer in the project. It got removed in
7f12366. It should probably also be removed from the types.

* Parameterize `CanceledError` in `isCancel`

Thanks to @samavati for the suggestion.
