When selecting a package from "All" in the package manger if an update is available clicking the "View updates" button will take you to the docs, not the change list.

Repro steps:
- Open Unity with any project
- Open the package manage (Window > Package Manager)
- Select "All"
- Select "Ads" or "Analytics"
- Click the "view updates" link on the right hand side of the menu
Notice issue >> The button takes you to the Unity feature documentation and not any change list.

In Unity 2018.3, the issue presents itself as a missing "View Change log" link
