With LH v8.1.3 supporting Fulu-on-Gnosis, we no longer need these DB migrations. All Lighthouse nodes running in prod will soon be updated to LH v8.0.0+ and schema v28+. This PR helps with Gloas fork choice changes, by allowing us to avoid updating old schema migrations when adding V29 for Gloas: - https://github.com/sigp/lighthouse/pull/9025 Co-Authored-By: Michael Sproul <michael@sigmaprime.io>
