devops(docker): push focal images to CR (#3950)

This will end up in the following Docker tags:
- focal <- new
- bionic < old as before
- latest <- old as before, keep bionic for now until EOL is reached
- v1.4 <- old as before, is bionic
- v1.4-focal <- new, is focal

Depends on https://github.com/aslushnikov/devops.aslushnikov.com/pull/3 to ensure it works.
Relates to https://github.com/microsoft/playwright/issues/3791.
