The phrasing "corner of the screen" wouldn't be accurate when the user
is doing a split screen or if the window or app is not taking up the
whole screen. Also, the use of "lower/upper" and "top/bottom" is not
consistent.
This standardizes on "corner of the app" and "bottom/top" when
referring to the location of app features on Desktop, Web, or Mobile.
Removes unnecessary mention of mac keyboard shortcut because the
documentation updates when a mac keyboard is detected.
Also, removes reference to accessing group private messages from
the right sidbar.
This better matches the title of the page and more generally our
conventions around naming /help/ articles. We include a redirect
because this is referenced from Welcome Bot messages, and we
definitely don't want those links to break.
