[DOCS-3194] Generate API docs for JS driver

[jrodewig]

Ticket(s): DOCS-3194

IMPORTANT:
I don't have access to Concourse pipelines so I'll need someone to test those changes for me.

Problem

We don't currently publish API reference for the v10 JavaScript/TypeScript driver.

During recent onboarding interviews, some customers have requested these docs.

Solution

• Use TypeDoc to generate API reference from TypeScript source and comments.
• Incorporate publication into the Concourse pipeline
• Host the docs on GH pages (via the gh-pages branch).

Result

The API docs will be available at https://fauna.github.io/fauna-js/.

I've already backfilled docs for the current release (2.2.0) in the gh-pages branch, but I'm holding off on publication until this PR is approved.

Testing

I've manually tested by running npm install && npm run doc to generate the files.

LGTM. Since the doc publishing is after publishing, we'll have to test the pipeline after merge and flush, which is fine I think. If it ends up failing, we can iterate with a dummy pipeline to get it right and PR the fix once.

Sounds good to me. Thanks @pnwpedro!
