**Other notes for review**

a node that is in syncing or optimistic status isn't fully ready yet. we
don't have a is ready endpoint, but I think having the gRPC match more
closely to
[/eth/v1/node/health](https://ethereum.github.io/beacon-APIs/?urls.primaryName=dev#/Node/getHealth)
would be good. This endpoint is only used internally as far as I can
tell.

this is prerequisite to https://github.com/OffchainLabs/prysm/pull/16215

tested via grpcurl against a syncing hoodi node
