Reinstate bash code to generate xauth file for sharing with the container

For some reason this was removed in an earlier commit relating to adding
jupyter notebook runtime mounting with no indication as to why.
Interpreting this as a mistake as I can confirm that X-pass through
graphics tools no longer work with the current setup, but renew working
when adding back in proper temporary xauth files for the containers to
use.

Added a note that we currently only support a pip-installed
docker-compose tool.

 otherwise an authentication token cannot be retrieved.
