Currently Docker will error and exit because `data` directory is not created.
This commit adds automatic `data` directory creation to Dockerfile so that the following docker command will not error.
```
docker run --detach --publish 5000:5000 --name lnbits-legend --volume ${PWD}/.env:/app/.env --volume ${PWD}/data/:/app/data lnbits-legend
```
