version-check should not always report a height of 1 for Sei pebbledb backend

[pharr117]

The version check container is always reporting a height of 1, even when using the Sei pebbledb backend and specifying the databaseBackend: pebbledb field in the chain spec.

1. Configure a sei node to run the latest version

- height: 84914892
  image: ghcr.io/strangelove-ventures/heighliner/sei:v5.1.0

2. Set chain spec databaseBackend to pebbledb

spec:
  chain:
    databaseBackend: pebbledb

3. Check the command created on the pod description to ensure its set to pebbledb

Command:                                                                                           
       /manager
       versioncheck
       -b
       pebbledb

4. Observe version check logs
