Documentation missing addEventListener and removeEventListener for JitsiTrack

[icanc0]

Description

JitsiTrack documentation

Under the documentation for JitsiTrack, the addEventListener and removeEventListener functions are missing.

Current behavior

The example in this project calls JitsiTrack.addEventListener, and the types does contain addEventListener under the JitsiTrack class. But such reference does not exist in the documentation.

Expected Behavior

The documentation contains info about event listeners under JitsiTrack.

Possible Solution

Add documentation under JitsiTrack, just like under JitsiConnection and JitsiConference.
