test(e2e): wait for theme-directives.html

Browse Source 
The `theme-directives.html` test currently sometimes takes a screenshot
before all of the Mermaid diagrams have completed rendering.

We can use the `urlSnapshopTest()` helper function, which waits until
a `.rendered` property exists on the page.
