Windows Terminal 1.14.1861.0

What's new in this version:

New:
- Terminal now has better support for xterm's "Alternate Screen Buffer"
- Console application windowing will now work more consistently within Terminal: when an application requests that it be hidden or minimized,
- we will minimize the associated terminal window.
- Terminal can now pass xterm focus events on to connected client applications
- We've added a new experimental setting, experimental.useBackgroundImageForWindow, that lets you use one image as the background for any number of panes
- You can now change the bell sound with the profile.bellSound setting
