Fix spec for summarization and translation outputs (#503)

Output key must be `summary_text` instead of `generated_text`. See
https://huggingface.co/docs/api-inference/detailed_parameters#summarization-task.

**EDIT:** same for `translation`. See
https://huggingface.co/docs/api-inference/detailed_parameters#translation-task.
