test: pick up cosmos-sdk with more abci flag tests (#9263)

closes: #9224

## Description

Pick up new version of cosmos-sdk that includes more tests and

### Scaling Considerations

If the setting is used to revert to the "local" client, query throughput
drops dramatically.

### Documentation Considerations

Docs added to TOML template, but this is an expert-level switch and no
one should use it without a good understanding of the impact.

### Testing Considerations

N/A

### Upgrade Considerations
