Add corporate sponsorship page

Reticketing from LI:

Open Source Endowment is very excellent work. Do you have info on the difference between corporate and individual participation?

Like should I advocate for my company to donate and then I would participate on behalf of them, or should I consider donating individually?

@vinogradovkonst Thoughts?

In a nutshell, the key difference is that corporate donors will get more visibility with our audience (we will intentionally highlight them), but unlike OSE members, they will not have the right to participate in the governance of the endowment. Using a business analogy, individuals are more like "shareholders," and companies are more like "clients" for OSE.

We need to add a page with a corporate sponsorship offering on our website!
