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

[nflaig]

Motivation

• Clarify use of 206 status code for node health. ethereum/beacon-APIs#442

Description

getHealth returns 206 status code if EL is syncing / optimistic

Closes #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.

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.

• Clarify 206 health status if EL is offline ethereum/beacon-APIs#455
