chore(docs): moving typescript docs into own section

[boyney123]

The docs are getting re-looked and updated slightly to help with the flow. Part of this is moving TypeScript docs out of the main project flow (for now), this will create a new section /docs/typescript and things will continue to work, but the main project will no longer point to these files, but will still be indexed.
