AIP: Whitelist Infura Nova Validator

Infura is in my knowledge one of the most reliable provider out there, and also well known in the industry. While this is just a formality, obviously needs to be rectified so we can register them. Voting for.

Not sure if could be maybe a situation in which we also want to review how we handle onboarding/offboarding of infra provider, to avoid this happening again in future (but maybe as @cliffton.eth said was just an oversight and nothing more)
