test(e2e): Delete `create-next-app` test

[github-actions]

Note

The pull request "test(e2e): Delete create-next-app test" was created by @chargome but did not reference an issue. Therefore this issue was created for better visibility in external tools like Linear.

This test did not cover any test cases that we have not already in place in other test apps, apart from testing a navigation transaction on pages router, which makes this test basically a waste of resources.

• Moved the navigation test to nextjs-pages-dir
• Deleted the create-next-app test
