Backport 5f4b8fc from #13457


What this PR does / why we need it:

The initialisation of the BloomStore service failed with a panic if the index gateways were configured to use ring mode.

This happened, because the bloom store requires to wire up the configuration for the shipper store, see
https://github.com/grafana/loki/blob/1a508b0aa/pkg/loki/modules.go#L864-L867

At this time, the index gateway ring manager wasn't initialized yet, leading to a nil pointer dereference.

This PR fixes the issue by adding the index gateway ring as dependency of the bloom store so it gets initialised first.

Checklist

  • Reviewed the CONTRIBUTING.md guide (required)
  • Documentation added
  • Tests updated
  • Title matches the required conventional commits format, see here
    • Note that Promtail is considered to be feature complete, and future development for logs collection will be in Grafana Alloy. As such, feat PRs are unlikely to be accepted unless a case can be made for the feature actually being a bug fix to existing behavior.
  • Changes that require user attention or interaction to upgrade are documented in docs/sources/setup/upgrade/_index.md
  • For Helm chart changes bump the Helm chart version in production/helm/loki/Chart.yaml and update production/helm/loki/CHANGELOG.md and production/helm/loki/README.md. Example PR
  • If the change is deprecating or removing a configuration option, update the deprecated-config.yaml and deleted-config.yaml files respectively in the tools/deprecated-config-checker directory. Example PR
