fix: Add missing workspaces-config label to vscode-editor-configurations ConfigMap (#3072)

The vscode-editor-configurations ConfigMap example was missing the
app.kubernetes.io/component: workspaces-config label. Without this label,
the ConfigMap does not propagate correctly to user namespaces, preventing
the editor configurations from being applied across workspaces.

This change adds the missing label to align with other ConfigMap examples
in the documentation (manage-extension-installation.adoc and
configuring-a-user-namespace.adoc).
