Error upgrading BeaconState

### Describe the bug

There is a TODO when upgrading state from capella to deneb: https://github.com/ChainSafe/lodestar/blob/8ed9109ddd394e6406c3c4feefb9140d71e88082/packages/state-transition/src/slot/upgradeStateToDeneb.ts#L28

if we migrate this way:
```
stateDeneb.latestExecutionPayloadHeader.excessBlobGas = BigInt(0);
stateDeneb.latestExecutionPayloadHeader.blobGasUsed = BigInt(0);
```

then got this error in spec test:
```
Error: LeafNode has no left node
❯ LeafNode.get left [as left] ../../node_modules/@chainsafe/ssz/node_modules/@chainsafe/persistent-merkle-tree/lib/node.js:109:15
❯ Object.getNodeAtDepth ../../node_modules/@chainsafe/ssz/node_modules/@chainsafe/persistent-merkle-tree/lib/tree.js:280:44
❯ CustomContainerTreeViewDU.set [as excessBlobGas] ../../node_modules/@chainsafe/ssz/src/viewDU/container.ts:193:52
❯ Module.upgradeStateToDeneb ../state-transition/src/slot/upgradeStateToDeneb.ts:34:56
```
