.js dist directory & build

[chuck-adaptive]

Repro -

• yarn build
• python -m build .
• twine check dist/*

Result: Checking dist/index.js: ERROR InvalidDistribution: Unknown distribution format: 'index.js'

This is definitely what's expected from source - the webpack build creates a dist directory, and the the python build is output to the same directory. I was able to publish and use my widgets by moving the python artifacts to a new directory and deploying that one.

• Does the Webpack configuration need updating? I see the dist dir is included as part of the files in the package.json
• Can someone explain the duplicate package.json? When I build - it is copied over to {{project name}}/labextension/package.json
