Updates the video link to a high definition video (#967)

* Updates the video link to a high definition video for setting the SPOTIPY_CLIENT_ID and SPOTIPY_CLIENT_SECRET values and authenticating. The old video was getting some complaints about people not being able to read the text (since it was low quality), so I've re-recorded it and replaced it with this new version.

* Adds changes to Chanelog
