boards: st: sensortile_box_pro: remove hts221 sensor

Remove HTS221 sensor support from sensortile_box_pro as it has been ruled
out from final version. In fact, HTS221 is in the process of being
terminated and is not recommended for new design. The candidate replacement
is SHT40 from Sensirion, which is available also as a DIL24 adapter, which
can be plugged on sensortile_box_pro board.
