Couple of Notes in the [Diagram Guide](https://kubernetes.io/docs/contribute/style/diagram-guide/) include mention of the Hugo Mermaid shortcode. This generates a syntax error. Appears that Hugo interprets this as a Mermaid diagram.
```
{{< note >}}
You must include the `{{</* mermaid */>}}`, `{{</* /mermaid */>}}` shortcode
tags at the start and end of the Mermaid code block. You should add a diagram
caption below the diagram.
{{< /note >}}
```
This PR removes the `{{< mermaid >}}` mention inside the `{{< note >}} so that Hugo does not attempt to render a diagram.
