chore(build): remove azure ubuntu package mirror in CI because it's broken (#7043)

Our api builds started failing on ubuntu because they couldn't install libsystemd. They appear to be hitting the package mirror http://azure.archive.ubuntu.com/ubuntu/ which as of 10 33am est today appears to have all content removed from the pool/ path.

This removes that mirror from the sources list and hopefully forces a fallback to another mirror that isn't broken in such a way.

Works around actions/runner-images#2104
