* Alerting: Update RuleGroupConfig definitions with missing fields
This update adds previously missing fields to the `RuleGroupConfig` structs to
ensure compatibility with external Prometheus-like rulers.
Includes:
- `labels`: per https://github.com/prometheus/prometheus/pull/11474
- `remote_write`: per https://github
.com/grafana/mimir/blob/56f33fed6254fee5a53bde1eab36c604863e3d5f/pkg/mimirtool/rules/rwrulefmt/rulefmt.go#L16
Note: This does not add full support in Grafana; it only allows these fields to
pass through the alerting proxy without causing unmarshal errors when using
external rulers.
* Update OpenAPI spec
