Tidying up after the analytics install

Removes the setup guides the PostHog installer left in the repository, now that the site's own analytics design replaces them.

Nothing on the site changes.

Behind the scenes

The PostHog installer (#100) left a small folder of its own setup guides in the repository. They describe the default-settings setup that the telemetry build replaced: one init in the analytics provider, cookieless, with autocapture off. Left in place, a future coding session could follow them and reintroduce a second init with cookies and autocapture. The folder is gone; specs/product/telemetry.md is the reference.
