feat(en): Check commitment allonside with roothashes (#4492)

## What ❔

During the reorg detection take into account not only root hash, but the
whole commitment

## Why ❔

We have at least one example, where during wrong execution we have
correct root hash, but wrong commitment

## Is this a breaking change?
- [ ] Yes
- [ ] No

## Operational changes
<!-- Any config changes? Any new flags? Any changes to any scripts? -->
<!-- Please add anything that non-Matter Labs entities running their own
ZK Chain may need to know -->
