Documentations doesn't cover that can add labels to a portal.

[GrahamDumpleton]

Describe the bug

A TrainingPortal resource can have labels independent to Kubernetes labels. The documentation doesn't seem to mention this.

spec:
  portal:
    labels: {}

Note that this is different to ability to add labels to specific workshops hosted by a training portal.

spec:
  portal:
    workshop:
      defaults:
        labels:
        - name: difficulty
          value: easy
  workshops:
  - name: lab-asciidoc-sample
    labels:
    - name: difficulty
      value: hard
  - name: lab-markdown-sample
