🌱 (chore): remove unnecessary trailing newlines and redundant blank lines (kubernetes-sigs#4664)

Cleaned up redundant blank lines and unnecessary trailing newlines across various files,
including test suites, scaffolds, plugin templates, and documentation scripts. This improves
code consistency and reduces visual noise, particularly in generated and test-related files.
