Each Ubuntu and Debian release has a code name. Ubuntu 18(bionic), Ubuntu 20(focal). This adds the Dockerfile for Ubuntu20.
Next steps and follow up changes:
- add it to the devops site, so we are sure all tests are passing, locally they did
- deploy it to the MCR, naming needs to be clarified, probably just as "focal".
This naming schema allows us in the future to add Debian support too. But we should wait until Headless WK is fixed.

This patch:
- updates docker seccomp profile to use a slightly modified default docker
profile
- removes SUID sandbox documentation since it doesn't seem to work
References #2745
This patch bakes browsers into docker image.
Important observations:
- We now re-build docker image everytime we roll browsers.
- Docker image size almost doubles: from `225MB` to `496MB`.

Has some overlaps with the troubleshooting doc, which I plan to clean up in a subsequent PR. This first version of the doc has a feel of "build-your-own" with our sample configurations. Over time we can tweak the level of hand-holding for the best user experience to get started with CI.
Fixes#1103
