Upgrade CI to Ubuntu 20.04 LTS (Focal) (#1183)

# Why
On one hand Ubuntu18's free LTS cycle is ended, and on the other hand Ubuntu18 does not support nodejs greater than v18.
# What's changed.
1. update the Linux Docker image to buildpack-deps:focal
2. some compatibility changes
3. use the new recommended way to install Docker ([see here](https://docs.docker.com/engine/install/ubuntu/))

See #1173
