Add mention of known issue: "Now Playing" widget interprets Microsoft Teams call notifications as media (MS's fault)

[gpicc]

As per title, the Now Playing widget interprets Microsoft Teams call notifications as songs. After the call is ended, the widget is stuck on the touchbar until the Microsoft Teams app is killed. By pressing on the widget, the call sound is reproduced, despite no call is incoming.

This is an issue with Microsoft Teams. Mac OS also interprets it as a song, go to the control centre and you'll see it showing as media. If Mac OS sees something as media so will pock.

Thank you @cshariq for your clarification. What do you think about mentioning this problem somewhere in the documentation/README?
