Sync Climate min/max temp with Google Assistant

[hookedonunix]

Proposed change

A change to the TempetureSettingTrait in the Google Assistant integration to also return the min_temp and max_temp attributes during a sync request. Both temps are converted into Celsius for the request and tests have been modified to suit this change.
I couldn't see any documentation that makes a note of this functionality.

This was identified by @balloob during this PR for the water heater platform.

The second commit fixes some missed code coverage I found on the TemperatureSettingTrait while testing. Happy to break that into another PR if that is preferred though

Confirmed working with the Google Home app 👍

Also, this appears to fix #92661 without having to disable local control 🚀
Edit: It doesn't fix local control.

Cheers! That local control issue looks painful
