docs: Add docs generation

[onnovisser]

Description

Use Typedoc to generate docs in a way that can be easily consumed in the Slate documentation. Moves around a few types and makes sure types are exported, so Typedoc picks up on them.

#2571

Includes a Github Workflow for updating auto docs and triggered on push to main. It will:

• run yarn gen:docs
• add, commit and push docs to sdk repo
• trigger a script that copies the docs into sdk-docs and opens a PR with the changes
  PR will need to be approved by team members

Example PR: centrifuge/sdk-docs#11

[github-actions]

Auto-bumped version for release, this cannot be the last commit as bots can't trigger the workflows to pass the PR checks
