Typo in README.md - XAUTHORITY

[TomHutter]

In Section Manually running with docker run commands there seems to be a typo with the XAUTHORITY volume:

docker run -it \
  --rm \
  --hostname="$(hostname)" \
  --env="DISPLAY" \
  --volume="${XAUTHORITY:-${HOME}/.Xauthority}:/root/.Xauthority:ro" \
  --volume="/tmp/.X11-unix:/tmp/.X11-unix:ro" \
  scottyhardy/docker-wine /bin/bash

This works:

docker run -it \
  --rm \
  --hostname="$(hostname)" \
  --env="DISPLAY" \
  --volume="${XAUTHORITY}:/root/.Xauthority:ro" \
  --volume="/tmp/.X11-unix:/tmp/.X11-unix:ro" \
  scottyhardy/docker-wine /bin/bash

They should both work. This part basically says if there is no value defined for XAUTHORITY then use the default of ${HOME}/.Xauthority instead:

${XAUTHORITY:-${HOME}/.Xauthority}

You've just replaced this with ${XAUTHORITY} which still works in your case, but the version above is a more general solution that works on both Linux and macOS.
