ethereum-genesis-generator is broken

A new version of the ethereum-genesis-generator was pushed a few hours ago (here) and now the module is broken. It fails with this error:

This genesis_timestamp is probably something new that was added to the generator, we should update the module accordingly. cc @parithosh in case you followed what was changed in there.

Metapoint on this, the reason why it gets broken randomly is because we pin latest for all the images we use. We should pin a certain version to make sure things don't randomly start breaking. That being said, it seems in thie case the generator only published a latest version on docker hub, so we can't really pin a version here :(
