add humidity to climate card and history

[oliverrahner]

I have some thermostats for floor heating, which also provide data on current humidity. The integration puts that info into the climate entity correctly:

But I see that data neither on the dashboard card, nor in the device's info and, consequently, also not in the History, where I would like to have it most of all.

Dashboard Card:

Info:

History:

History:

I was also looking for this feature. I found issue #4740, which seems to have been erroneously closed. Humidity is part of the climate entity and should be visible in the thermostat card.

Any comment from @zsarnett on why he closed #4740? The closing comment seems to confuse which card/issue was being addressed.
