update to v1 of LC REST API (#4232)

The LC REST API has been merged into the ethereum/beacon-APIs specs:
- https://github.com/ethereum/beacon-APIs/pull/247

Update URLs to v1 and update REST tests. Note that REST tests do not
start with Altair, so the tested BN will return empty / error responses.
