🔧 chore(grafana-k8sgpt-dashboard.yaml): simplify namespace configuration

The namespace configuration for the Grafana dashboard has been simplified by removing the unnecessary namespaceSelector block. Instead, the namespace is directly set using the .Values.grafanaDashboard.namespace value, falling back to the default namespace if not provided. This change improves readability and reduces complexity in the configuration file.
