fix: Update Nethermind scripts for Holocene (#92)

Recently we've added support for the upcoming Optimism hard-fork
Holocene in Nethermind
(NethermindEth/nethermind#7761) and the OP team
suggested us to use OP's kurtosis package to test it.

We found a couple of issues when trying to set up an enclave due to
certain changes to other fork's timestamps which would trigger an error
in Nethermind. To fix that, one of our developers (@flcl42) updated the
`gen2spec.jq` script which fixes the above mentioned issue.
