We run apt_update once with chef and we already update the cache directly on the container at start. We don't need to try to do the same thing 3 other times.

The pinned version of Rubocop in some of the TK examples' Gemfiles
was a very old version with known vulnerabilities. Since these are just
examples and have no Rake tasks that rely on them, I removed rubocop
outright from the example Gemfiles.
