Powerwall function get_battery_data not working

[gmcluhan]

As of October 5, 2023 it appears the get_battery_data function isn't working anymore.

Traceback (most recent call last):

I see that function has been removed from the code base. It would be good to update the documentation that this has been removed. Along with that documentation it would be great to see how to use get_site_info() and get_site_data() as I think those are the replacements.
