Rationale for this change

Inspired by @phillipleblanc's comment on #12357 (comment) let's make it clearer that DataFusion is targeted at people building other systems

  1. The main website https://datafusion.apache.org/
  2. The docs.rs page: https://docs.rs/datafusion/latest/datafusion/index.html
  3. The github repo: https://github.com/apache/datafusion/

I think it could be argued that we should move this content out of the github readme.md leave a link to the main website https://datafusion.apache.org/ 🤔
