Bump DB schema to v25 (#7666)

When we removed the eth1 data, I wrote a v25 schema upgrade to delete the data on disk:

- https://github.com/sigp/lighthouse/pull/7133

However, I forgot to update the current schema version, so this change was never actioned.


  This PR updates the current schema version to v25 so that the migration runs.
