Checklist

• Reviewed the CONTRIBUTING.md guide (required)
• Documentation added
• Tests updated

• 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

Besides fixing the unit tests, we need to expose the new limit in the LokiStack CRD.

Almost there. Please run make bundle-all to generate all CRDs and bundles.
