* add max_new_tokens=20 in test pipelines

* pop all kwargs that are used to parameterize generation config

* add class attr that tell us whether a pipeline calls generate

* tmp commit

* pt text gen pipeline tests passing

* remove failing tf tests

* fix text gen pipeline mixin test corner case

* update text_to_audio pipeline tests

* trigger tests
