Add one-line dev rake task to setup Product Analytics

What does this MR do and why?

This MR adds a one-line dev rake task to setup Product Analytics on a local GDK instance.

Usage example:

bundle exec rake gitlab:product_analytics:setup\['gitlab-org'\]

GDK docs will be updated in a follow-up MR: Add one-line setup to product analytics dev docs (gitlab-development-kit!3507 - merged).

This was heavily inspired by Introduce one-line rake task to setup GitLab Du... (!136647 - merged).
