Since `QueryBrowser` component was exposed in the console-dynamic-plugin-sdk we should showcase its usage.

One of the use cases should be to render a chart, using the `QueryBrowser` component, in a dashboard card. For the we would use the console.dashboard/card console extension.

AC:

• Update the dynamic-demo-plugin with the `console.dashboard/card` extension, where the QueryBrowser component will be used to render a chart. Part of the story is also to find a simple query that the `QueryBrowser` component will be fed with.
• Add cypress test for the chart.
