Clojurians Log v2

Pushed another Docker related draft blog to https://practical.li/blog-staging/, this time on installing Docker Community Edition & Docker Desktop to Linux (Ubuntu, Regolith, Debian, etc) I found the Docker Docs had all the information, but spread across several pages and sections. Quite easy to get lost, so hopefully this is simpler. Update: all Docker blogs are published to http://practical.li/blog and expanded upon in https://practical.li/engineering-playbook/continuous-integration/docker/
