Typedoc is an item undergoing major improvement while also being integral to all of the Dojo 2 projects. It would be good to have a set of integration tests to ensure given a set of inputs that we can produce a set of desired API documentation. There is currently a basic typedoc integration test that validates building API documentation outside of the current working directory. We should add tests that:

• test typedoc's externalPattern and excludeExternals option
• test typedoc's exclude option
• test the creation of JSON with typedoc
• test typedoc's includeDeclarations option
