Unsure, but documentation for change event seems wrong for md-tabs

[Dakotys]

Description

In documentation are mentioned link link2 selectedItem property and other properties that no longer exist, they have been at some point replaced with activeTabIndex link.
Also maybe example of eventListener directly in documentation for Events could be helpful. (I wouldn't have to question my js knowledge and whether I am doing something wrong and instead would check potention flaws in source code first. )<3

Thanks for the issue, and sorry for the delay! I'm sending out #5627 to fix the docs.

For the event doc examples, I agree that would be a good enhancement! Maybe add a comment on Better docs needed (#5407)?
