PR Summary

The package.json info is now available in the extension context, this avoids a round trip. Note there is no validation on the import of the information (there wasn't before either), but it's very unlikely to surface a null or undefined, or have that affect operation of the extension (famous last words).

Quick note that this API is also available in 1.82 which is what Azure Data Studio is on so that should be fine but I haven't directly tested it.
