Merge pull request 'chore(deps): update docker.io/library/node docker tag to v24.8.0' (#68) from renovate/container-images into master

The following patch extends the chart to automatically roll the deployment, when
one of the configurations, stored in a config map or secret, has been changed.

The implementation add annotations which triggers `helm update` or ArgoCD to
roll the deployment. Further information can be found on the official helm
website:

+### Network policies
+
+Network policies can only take effect, when the used CNI plugin support network policies. The chart supports no custom
+network policy implementation of CNI plugins. It's support only the official API resource of `networking.k8s.io/v1`.
+
+The object networkPolicies can contains multiple networkPolicy definitions. There is currently only one example
+predefined - it's named `default`. Further networkPolicy rules can easy be added by defining additional objects. For example:
+
+> [!NOTE]
+> The structure of each custom network policy must be equal like that of default. For this reason don't forget to define
+> `annotations`, `labels` and the other properties as well.
+
+```yaml
+networkPolicies:
+  enabled: false
+  default: {}
+  my-custom-network-policy: {}
+```
+
+The example below is an excerpt of the `values.yaml` file. The network policy `default` contains ingress rules to allow
+incoming traffic from Prometheus.
+
+> [!IMPORTANT]
+> Please keep in mind, that the namespace and pod selector labels can be different from environment to environment. For
+> this reason, there is are not default network policy rules defined.
+
+```yaml
+networkPolicies:
+  enabled: true
+  default:
+    enabled: true
