Handle local type definitions in Monaco

[josephjclark]

Description

This PR enables local typedefs to be loaded when LOCAL_ADAPTORS=true

I told Frank not to worry about this and then SUDDENLY I need it today.

By default the monaco code assist and adaptor docs will both call out to unpkg for types. Not ideal if you're trying to test typedefs in a local adaptor build.

This is a super PR which roughs in support to fetch typedefs from the monorepo using a proxy server

Actually, at the moment I'm using npx serve --cors -l 5000 from inside adaptors to create a local server. I'll need help to setup a proxy inside Lightning.

TODO

• Fix adaptor docs
• Tidy implementation
• Setup a proxy server in lightning which serves from the monorepo
