Add `views/pages` to the default testing page paths

[innocenzi]

This PR adds the resources/views/pages path to the default testing page paths.

The reason for this is that I personally believe pages should be in the resources/views/pages directory instead of the resources/js/Pages one:

• Having js as the main directory does not make much sense, as it is common to not have any JavaScript files
• I dig the kebab-case convention (but this is compatible with camelCase too), inspired by codebases like Vite, Vue and the default Laravel blade one
• I'm promoting this architecture with Laravel Vite, but I kept resources/js in the defaults too
• My Inertia preset scaffolds this architecture as well

Note that this is just a convenience addition to avoid having to fix it up manually. It doesn't change the previous behavior and should not bring any false positives either.
