WEB: Update sponsors in website

[datapythonista]

Still waiting for the logos of the new sponsors, and final confirmation that we want to replace Ursa Labs by Voltron, but opening early in case there is feedback.

I forgot about Nvidia, sorry. Thanks for the heads up, added it now.

This should be ready now. This is how the home page look with the new sponsors:

@mroeschke I found the nvidia logo online, I think it should be fine.

I watched @jreback recent talk, and I'm wondering whether we should also add USC (who sponsored @jbrockmendel to work on the non-nanosecond stuff via Quansight), and NASA (I don't know much about that grant). No strong opinion, but if we add them let's do it in a follow up PR, since getting the logos takes a while and this is ready now.

Thanks. I am still inquiring within my company to get approval to use the logo, but if you'd like to merge this and add Nvidia's logo (and the others) in a followup I would be fine with that

[datapythonista]

I'll split this in two and have nvidia in a separate PR, so we can get the rest merged, and nvidia is ready for whenever the decision is made. Thanks for letting me know.

@datapythonista I just got approval now that the Nvidia logo usage is good!
