Migrate NodeTestCase to static data providers
PHPUnit 11 requires data providers to be static. This PR prepares our abstract `NodeTestCase` by deprecating the non-static `getTests()` and adding a static `provideTests()` as a replacement. I've also added PHPUnit attributes which newer PHPUnit releases prefer over PHPDoc annotations.
