Make installation on Ubuntu easier

[davidzchen]

Description of the feature request:

Many other projects only require running one command to add a ppa, for example for diff-so-fancy:

sudo add-apt-repository ppa:aos1/diff-so-fancy

It would be a better user experience if we could do the same to install Bazel on Ubuntu

If we consider doing something like this we might consider doing it for Bazelisk instead of Bazel itself.

I think it would be better to have packages for both Bazelisk and for Bazel.
