Pysyft: Update Org. contributions on the README

[LaRiffle]

Dozens of organizations have been contributing to PySyft development, however only 4 of them are represented on the main page. Although this distinguishes early supporters, it might be time to update the page so that Udacity, CoMind, Arkhn, DropoutLabs (CapePrivacy) can be joined by all the great support we currently have.
A simple item list might be sufficient, i'm not sure we need super fancy logos.

@LaRiffle what other organisations do we need to add apart from the current four(udacity & co) ? Would love to work on this

We will need to get this updated prior to course launch. I'll work to resolve ASAP

Thats really awesome @cereallarceny I rekon we should add that for sure, but does it also cover things like Organisational contribution / sponsorship credits? I think for this ticket we just need to know what other orgs to give shout-outs 📣 to since the last version README.md.
