Docs for current and target temp scale/offset.

[illia-piskurov]

Proposed change

The documentation previously stated that scale and offset only applied to the target temperature.
This was incorrect: in reality they apply to both target and current temperature.

This fix corrects the documentation.

There are devices that require different scaling for target and current temperatures (for example, Cooper air conditioners). People have also reported this limitation on the forum:

This was also discussed in PR: home-assistant/core#135848.

The documentation change is ok, but the PR test seems wrong:

"Now scale and offset is applied to both target and current temperature at the same time"

as far as I can see, scale and offset are applied to target and current temperature on dev, so what have changed in code "now" signals a change, but if the code have not changed then please reword it accordingly.

It is correct that the documentation was incorrect, and it is now corrected.

Once the PR text is updated, ping me as reviewer and I will approve the PR (remembering the code PR is still open).

LGTM, thanks.

(waits for core PR to be merged).
