Material-ui: Publish documentation as docset

[duncanbeevers]

Standalone documentation browsing apps like Dash, Zeal, and Velocity use a documentation packaging format called docset

The excellent Material UI docs would be even nicer if they were published in the docset format, available for local+offline search and perusal.

• [x] I have searched the issues of this repository and believe that this is not a duplicate.

Summary 💡

Existing docs should be published and made available on the Kapeli/Dash-User-Contributions repository.

@duncanbeevers would you be interested in working on the problem?

For the others interested, please upvote https://github.com/Kapeli/Dash-User-Contributions/issues/2384. Hopefully somebody from the community will fill this gap :).

@oliviertassinari I pushed a minimal docset-generating branch here; https://github.com/duncanbeevers/material-ui-docs

It leverages the existing build+export functionality, and relies on a 3rd-party tool dashing to build the docset.
Here's a zip of the generated docset; material-ui.docset.zip

Steps to test

1. Clone repo + install dependencies
2. Install dashing
3. Generate docset $ yarn docs:docset
4. Install docset by double-clicking in Finder, or adding manually in Dash

I'll see if I can find some more time to work on this. Obvious next steps might be:

• Replace dashing Go binary usage with a node package like docset-generator.
• Make single-language-selection explicit, instead of being driven implicitly from PULL_REQUEST=true environment variable.
• Create a new rendering target where site-layout stuff like side and header bars are omitted.
