The @dataProvider annotation should be a static function, check and make data provider in the extension, at least:
- ChangeOpLanguageTest with invalidEntityProvider
- ChangeOpLemmaEditTest with invalidEntityProvider
- ChangeOpLemmaRemoveTest with invalidEntityProvider
- ChangeOpLexicalCategoryTest with invalidEntityProvider
- InfoActionHookHandlerTest with handleProvider
- LexemeMetaTagsCreatorTest with provideTestGetMetaTags
static and adjust the usages (More infos at T332865).
