Remove mention and usage of Bazel Federation (#339)

It's currently a stalled project so it's not useful for us to direct new users there in our README.
Separately it is harder to develop on rules_python since it is currently not self-contained.
For example it's hard to find or adjust the version of rules_pkg without looking/editing in the federation repo.
Tony says this is an okay change: https://github.com/bazelbuild/bazel-federation/commit/63f9746afd4e8564d1033c529ce5065f69d6c7f9#commitcomment-40577834
