TabbedPanel: Doc calling `switch_to` from `__init__` (#7342) 

* Fixed reference

Previous reference didn't link to anywhere, and now it links to the
dev-install page.

* Added link for example usage

As discussed in the issue #3493, when calling this method from the
python script, it has to be scheduled to the next clock cycle.

* Update kivy/uix/tabbedpanel.py
