Tabset Icon in Documentation not matching Component

### Issue type

Im submitting a request to change the icon of the tabset in the documetation. Everytime I search this component it takes forever to find, because it looks more like a toggle button than the tabset.

Adding this picture in case somebody does not know what I am talking about

I am not a graphic designer, but in my opinion it misses the text on the right and the color does not fit. This would be my quick and dirty suggestion.
