fix: getHealth returns 206 status code if EL is optimistic or offline

[nflaig]

Motivation

• https://github.com/ethereum/beacon-APIs/pull/442

Description

getHealth returns 206 status code if EL is syncing / optimistic

Closes https://github.com/ChainSafe/lodestar/issues/6664

[nflaig]

Something else to consider is if EL is offline, this is not clearly defined in the spec but Lodestar considers itself synced for 32 slots until head is too far behind but it's can't properly serve all requests, so it might be better to immediately return a 206 status code in that case as well.
