Improve Typescript docs

[isidorn]

Some ideas on how to improve typescript docs:

• Review current Typescript docs @gregvanl
  • Should some sections be moved into separate docs to not interrupt the flow
• Identify what docs are successful based on clicks for other languages @gregvanl
  • Add those docs for Typescript
• Identify situations in the product where we can link directly to docs (e.g. source maps not working) @isidorn
• Identify what are the common pain points of Typescript users so we consider covering that @isidorn

Greg did most of the work here. Closing as done sine no future action planned here right now.
