SERVER-72088 introduced a temporary feature flag to guard using a ShardRemote for the config shard in the ShardRegistry on a config server, `featureFlagConfigServerAlwaysShardRemote`. This was done instead of using the existing `featureFlagCatalogShard` flag because that one is temporarily disabled by default, but the ShardRemote changes are stable enough to benefit from coverage in the all feature flags variants. `featureFlagCatalogShard` is the true feature flag for this project, so we should replace `featureFlagConfigServerAlwaysShardRemote` with `featureFlagCatalogShard` once the latter is stable enough to be on by default.
