✨ [Tasks] JSON Schema spec for Inference types + TS type generation (#449)

# TL;DR

- Introduces specification for inference input/output types for each
task, in JSON Schema format
- Add a "script" to generate typescript code from that JSON spec using
[`quicktype-core`](https://github.com/glideapps/quicktype/tree/master/packages/quicktype-core)
- Introduces `quicktype-core` as a dev dependency (from our fork of
quicktype
https://github.com/huggingface/quicktype/releases/tag/pack-18.0.15)

# TODO

- [x] Add a `text2text-generation` task to serve as a "canonical
reference" for `summarization` & `translation`
- [x] Add a `text-to-audio` task to server as a "canonical reference"
for `text-to-speech`
- [ ] Code generation tweaks
   - [x] Change `any` types to `unknown`
   - [x] Generate output types for `sentence-similarity`
- [ ] Generate output types for `feature-extraction` -> Let's do that
later?
- [x] add placeholder specs
