J. Nick Koston	https://github.com/bdraco	Database schema v32 updates

For Home Assistant Core 2023.2 the database schema has changed.

This change affects custom integrations that do not use the recorder history API and access the last_updated, last_changed, or time_fired columns directly.

The documentation for the events and states have been updated and is available at the Data Science Portal.
