Problem Statement

Right now the users have to set the integrations by themselves. Better would be auto enabling it like Django.

Solution Brainstorm

Detect starlette and fastfapi python modules and if present enable the integrations. See other integration how they do it.
Also update the guide in documentation, the wizard and the static "for" pages to reflect this.
