fix(header): temporary disable skipping verification (#2456)

This PR disables skipping verification and accepts all the incoming non-adjacent headers. These headers will later be verified via adjacent verification and rejected if invalid. Test that proves that Syncer rejects and continues to work with a fault header: celestiaorg/go-header#76 Potential outcomes of doing so: celestiaorg/go-header#79 Additionally, the PR reverts the genesis hash change to the hash pointing to height 1. Supersedes #2449, which became zombie --------- Co-authored-by: rene <[email protected]>
