Improve Ginkgo/Gomega Test Practices in Scaffolded and e2e Tests

[camilamacedo86]

What do you want to happen?

Kubebuilder creates/scaffolds a lot of test code. This test code uses Ginkgo and Gomega. Some of the tests as written don't take full advantage of Gomega's testing framework. Since Kubebuilder is likely to introduce many developers to Gomega, it is important that the scaffolded code provides the best possible examples.

We should see that the tests scaffolded for end-users have this issue fixed already: testdata/project-v4/test.

What we need to do here is ensure that ALL our e2e tests are also following the same patterns as the end-user scaffolds. Therefore, the necessary changes must be implemented in: test/e2e.

Context

The context for this issue and similar discussions can be found here: kubernetes-sigs/kubebuilder#4135.

Tasks

1. Review and compare the test scaffolds in testdata/project-v4/test to ensure best practices in Ginkgo/Gomega are being followed.
2. Update all e2e tests in test/e2e to align with these patterns and provide the best examples for developers.
3. Validate that the tests maintain readability while leveraging Gomega's framework effectively.
