Backport 66b8c9b7738acd0e0616b88d35cf3ddc0df83e7e from #13221
What this PR does / why we need it:
Currently Loki's internal server instance is running by default in a panic: nil pointer dereference because along all the updates for 3.0.0, we missed to initialize this server properly:
The internal server in Loki is mainly used in mTLS setups on Kubernetes where we want to allow TLS-secured Readiness/Liveness-Checks without client certificates. Usually k8s readiness/liveness checks do not support mTLS.
[x] 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
