update go-eth2-client to qu0b/eip7928 with SlotNumber (EIP-7843) support

Fixes checkpoint sync for bal-devnet-2 by switching from pk910/go-eth2-client
(missing SlotNumber) to qu0b/go-eth2-client eip7928 branch which includes
both BlockAccessList (EIP-7928) and SlotNumber (EIP-7843) in the Gloas
ExecutionPayload types.
