Limit which tasks transformers has support for (#591)

Until now, the Hub assumes `transformers` has support for all tasks for
which there's API, such as `audio-to-audio` (and there's no
`AudioToAudioPipeline` in `transformers`). This list is derived from
https://github.com/huggingface/api-inference/blob/main/shard/app/validation/__init__.py#L24

This will hide widgets/snippets for tasks not supported here
