Autogenerate UI adapter props with ts-morph

[serikjensen]

This PR uses ts-morph AST to autogenerate prop documentation for the component adapters.

For more context on alternative approaches explored see the slack thread here.

The summary at a high level behind the decision to go this way:

• Using react docgen TS is not viable because it depends on interfaces being in the same files as components (which ours are not)
• Using typedoc with the markdown plugin is highly prescriptive about the output outputting to multiple files which we have little control over, it also fails to document our picked HTML props which is a pattern that is important to us to keep our component APIs aligned with the HTML spec
• Using typedoc directly you are still unable to document picked props and it is almost as much overhead as just using the AST

This approach uses ts-morph which allows us to get all props (including picked html props) and format them to a single file according to our needs. This is also an approach that requires the most custom config. In the event that this script proves brittle or challenging to maintain, we may ultimately need to revisit and just deal with the limitations of typedoc + markdown plugin. But team consensus was that we could give this a try and adjust as needed down the road.
