…hboard in values.yaml

The namespace field in the grafanaDashboard section of the values.yaml file is not needed as it is commented out and has no value. Removing it improves the readability of the file.

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.
