1. I don't see how any hotel can charge you, if you are forced to stay there against your will.
2. It would be ridiculously bad PR to charge quarantined hotel guests, who could easily go to the press and raise a fuss
However if you are stuck in country because of flight cancellations or the airline refuses to carry you, you are probably stuck making your own arrangements, although potentially the airlines would have "duty of care" responsibilities.
