Add SyncCommittee signature set in all block sigs

[dapplion]

Describe the bug

We do not include the SyncCommittee signature in this all blocks sig bundle

lodestar/packages/beacon-state-transition/src/allForks/signatureSets/index.ts

Lines 33 to 43 in 13bb120

	export function getAllBlockSignatureSetsExceptProposer(
	state: CachedBeaconState<allForks.BeaconState>,
	signedBlock: allForks.SignedBeaconBlock
	): ISignatureSet[] {
	return [
	getRandaoRevealSignatureSet(state, signedBlock.message),
	...getProposerSlashingsSignatureSets(state, signedBlock),
	...getAttesterSlashingsSignatureSets(state, signedBlock),
	...getAttestationsSignatureSets(state, signedBlock),
	...getVoluntaryExitsSignatureSets(state, signedBlock),
	];

Expected behavior

We must verify all signatures in a block
