#14011: Implement TreeItem.get_button_tooltip(column, idx).

Browse source 
When added to `TreeItem`, buttons are given tooltips. When returned via `get_button(...)`, however, the button is a `Texture` and the tooltip information isn't included.

For accessibility purposes, it is useful to have access to the tooltip text. As such, we can retrieve a button's tooltip to use as a button label.
