consider renaming Quay org to match the new GitHub org

[miabbott]

The containers that are automatically built and pushed to Quay live in the fido-fdo organization which doesn't map to the previous GitHub org where this repo lived (fedora-iot) nor the new org of fdo-rs.

i.e. quay.io/fido-fdo/owner-onboarding-server

Can we rename the Quay org to match the current GitHub org?

I think this would improve the association between the location of the containers and the location of the code.

(Proposed example: quay.io/fdo-rs/owner-onboarding-server)
