[CI ] Remove `past` in favor of `pat_key_values`
# What does this PR do?
Related to #20944, The `past` arg was removed.
Other tests might also pass! <|||||>_The documentation is not available anymore as the PR was closed or merged._<|||||>Git overides the `use_cache` arguments (only if labels are provided) to `False` see [here](https://github.com/ArthurZucker/transformers/blob/c2f9aacee9326b9db886036497a4d157666cb040/src/transformers/models/git/modeling_git.py#L1475-L1476). When generating, `use_cache` is set to false, but when we run `model.group_beam_search`, the ` self.prepare_inputs_for_generation(input_ids, **model_kwargs)` method forces `use_cache` to True see [here ](https://github.com/ArthurZucker/transformers/blob/c2f9aacee9326b9db886036497a4d157666cb040/src/transformers/models/git/modeling_git.py#L1516-L1534). 
EDIT: just update this tests will pass now. <|||||>The failing tests are unrelated, will merge
