E2E: fix test that opens page template

[tbradsha]

In WordPress/gutenberg#59792, the FSE page template selection was changed to use the DataViews component.

This PR updates the test that opens the page template editor.

Proposed Changes

I created a new FullSiteEditorDataViewsComponent, as DataViews will eventually be the new page/post listing component as well.

Note that I didn't get build out a ton of functions/specific selectors here, as the DataViews component has been evolving quite quickly, and we don't want to be continually adapting this test. Specifically, I didn't bother targeting the "Edit" button (which is selectively visible) or the actions dropdown (which also has changed several times). Instead I just made the test click the primary field text, which opens the template editor.
