Fix the Dog component to pass the example tests (#4539)
Fix the Dog component to pass the example tests (#4539)

The example tests in the `Testing loading states` and `Testing error states` section fail because they expect `tree.children` to contain `Loading...` or `Error!`.
However, the `Dog` component only renders a text when the query is its loading and error state resulting in the tests failing.
This fixes this issue by simply wrapping the text with `<p>` element.
