Update README.md and change default .env to .env.example

This will make it easy to clone the repository, and the custom .env will remain intact.

-> Please note that when accessing CKAN directly (via a browser) ie: not going through Apache/NGINX you will need to make sure you have "ckan" set up to be an alias to localhost in the local hosts file. Either that or you will need to change the `.env` entry for `CKAN_SITE_URL`

-> Using the default values on the `.env` file will get you a working CKAN instance. There is a sysadmin user created by default with the values defined in `CKAN_SYSADMIN_NAME` and `CKAN_SYSADMIN_PASSWORD`(`ckan_admin` and `test1234` by default). **This should be obviously changed before running this setup as a public CKAN instance.**
