This helps because we will always need the observer to be initiated, not only when the `openToBrowser` method gets called. Example: Opening a tab from the tab tray had it's own method for opening the browser, causing this to not be called.

The end result is that Android Studio can be used in Windows to build Fenix
when using the "local publish" workflow managed by settings.gradle -
android-components publishes automatically, although it's necessary to
manually public application-services because it doesn't build on native
Windows, only via WSL. So instead of trying to build it, it just
prints a message indicating the manual build is necessary.

This was previously regressed by having the RecyclerViews for "recent" and
"all" items put inside a HorizontalScrollView which would then prevent the
RecyclerViews from actually scrolling, recycling, showing new items.

As a quick solution that would keep the desired behavior the "all" items list
is now a child of a RelativeLayout which will allow it to load all items at
once and so all the share targets will be available to the user but which also
means no recycling.

The RecyclerView for the "recent" items uses a `RECENT_APPS_LIMIT = 6` so this
does not need the same "fix" as all the items would fit the screen without
any issue.
