Move talk page notification data from 'user-menu' to 'notifications'

**Note**: This change will affect the order of the yellow talk page
message notification on legacy Vector/other skins by moving it from
after the `#pt-notifications-notice` element to before the
`#pt-notifications-alert` element. This was done because the
notification is related to the list of messages that appear when the
bell icon is clicked so having it in close proximity to that icon is
hopefully more intuitive than having it next to the unrelated inbox
icon. [1]

Per T274428, we need this notification to be inside the `notifications`
array instead of inside the `user-menu` array.

Additionally:

* Per T274428, update the notifications message copy to "You have a new
Talk page message"

* Remove the `onPersonalUrls` hook method inside EchoHooks,
unregister its use as a hook in extension.json, and update its
references in Echo.
