[Bug] activate hook doesn't receive transition as an argument

[mehulkar]

The activate hook is called by the private enter method:

https://github.com/emberjs/ember.js/blob/v3.20.0-beta.2/packages/@ember/-internals/routing/lib/system/route.ts#L380-L384

which is called by the underlying router.js library

https://github.com/tildeio/router.js/blob/v6.2.5/lib/router/router.ts#L520

Passing along the transition would allow the activate hook to know if the leaf route was activated (i.e. if this.fullRouteName === transition.targetName).

I'm not sure if this is an oversight or not, but it did not seem significant enough to file a feature request / RFC.

Hmm, seems reasonable to me. Not sure exactly why we didn't do that before 🤔.
