Home Assistant Core 2021.3 requires a version key for custom integrations

Hi Filip,

The new Home Assistant Core 2021.3 requires a version key for custom integrations.

I'm getting the following warning:
WARNING (MainThread) [homeassistant.loader] No 'version' key in the manifest file for custom integration 'nhc2'. This will not be allowed in a future version of Home Assistant. Please report this to the maintainer of 'nhc2'

For more info, see: home-assistant/core#45919

thanks
