Use MAX_REQUEST_PAYLOADS in EnvelopesByRange

[jtraglia]

For some reason, we're still using MAX_REQUEST_BLOCKS_DENEB in ExecutionPayloadEnvelopesByRange. I believe we forgot to update this when adding the new config a while back. This would mirror ExecutionPayloadEnvelopesByRoot:

consensus-specs/specs/gloas/p2p-interface.md

Lines 618 to 649 in 7d5f334

	##### ExecutionPayloadEnvelopesByRoot v1
	**Protocol ID:** `/eth2/beacon_chain/req/execution_payload_envelopes_by_root/1/`
	For each successful `response_chunk`, the `ForkDigest` context epoch is
	determined by `compute_epoch_at_slot(beacon_block.slot)` based on the
	`beacon_block` referred to by
	`signed_execution_payload_envelope.message.beacon_block_root`.
	Per `fork_version = compute_fork_version(epoch)`:
	<!-- eth_consensus_specs: skip -->
	| `fork_version` | Chunk SSZ type |
	| -------------------- | -------------------------------------- |
	| `GLOAS_FORK_VERSION` | `gloas.SignedExecutionPayloadEnvelope` |
	Request Content:
	```
	(
	List[Root, MAX_REQUEST_PAYLOADS]
	)
	```
	Response Content:
	```
	(
	List[SignedExecutionPayloadEnvelope, MAX_REQUEST_PAYLOADS]
	)
	```

To be clear, these are the same value right now (128).
