Add webrtc-adapter for compatibility

https://github.com/webrtcHacks/adapter

From MDN: https://developer.mozilla.org/en-US/docs/Web/API/Screen_Capture_API/Using_Screen_Capture

Note: It may be useful to note that recent versions of the WebRTC
adapter.js shim include implementations of getDisplayMedia() to enable
screen sharing on browsers that support it but do not implement the
current standard API. This works with at least Chrome, Edge, and
Firefox.
