fix: startup warning about deprecated TEMP_FAHRENHEIT and TEMP_CELSIUS in 2024.1.6

[matthewbogner]

I am running HA Core 2024.1.6

Upon startup, I am seeing the following warnings. Seemed simple enough to just fix instead of opening an issue. This change (home-assistant/core#81006) was made in HA core in 2022.11, so this shouldn't reasonably be introducing any backward compatibility issues.
