[IT] Improve climate common names to avoid clashes with fan

[giobber]

Hi, thanks for all the great work for the italian language support

When i try to switch on or off a climate using the term "climatizzatore" or "condizionatore" HA keep trying to use a fan entity which never existed (I don't actually have any fan entity)

So for clarifying, when i ask:
Accendi il condizionatore in camera
Assist respond with:
Non conosco nessun dispositivo di tipo 'fan' (or something similar)

By looking in the default intents I understood that the terms "condizionatore" e "climatizzatore" are used either for fan entities and climate entities, which is not what I was expecting at all as I'm not sure I'll ever call a fan with these terms (but maybe it's a subjective thing, I don't know). In any case It seems odd to me that HA default to fail on first entity class assumption

For now I solved by removing the two terms from fan domain in my local _common.yaml file, a procedure which is hinted but basically not documented at all in the official documentation (https://www.home-assistant.io/voice_control/custom_sentences_yaml/)

Here are my configuration (in case I'm not the only one struggling with this)
The file should be saved in config/custom_sentences/it/_common.yaml, create sub-folders if needed

# config/custom_senteces/it/_common.yaml
language: it
expansion_rules:
  fan: "(ventol(a|e) | ventilator(e|i) | ventilazione)"
