Remove receptor from ecosystem

issue #208

[samccann]

fwiw I'm still not convinced removing it is the right thing to do here. As was mentioned on a previous related Pr - if it's in the ecosystem it's in the ecosystem. I disagree with us acting as gateways for what project is 'good enuf' to be on this page. Perhaps in a future iteration, we have this main ecosystem page, and then an 'incubator' page or something. Something to discuss in the new year as we tackle governance etc and can have guidelines on what belongs here on this page.

@samccann i believe we're not gating here. This case is rather exceptional as there's no value for outside users/contributors in seeing the project whatsoever.
It's used somewhere in AAP deep under the hood and, i think, the only reason it lives under the ansible org is that it must do so because of the legal requirements for OSS.
