Update files field in package.json

[compulim]

Fixes #4317.

Changelog Entry

Breaking changes

• Published NPM packages will now only includes /dist, /lib, and /src folders
  • Previously, /dist was missed from our NPM packages

Changed

• Resolves #4317. Updated package.json to allowlist /dist, /lib, /src, by @compulim in PR #4318

Description

Today, we didn't specify files field in our package.json.

However, we found that npm pack does not pack the /dist folder. It does pack /lib, /src and most files at the root.

Tomorrow, we are specifying files to include /dist, /lib, /src folders.

Design

We want to allow our web developers to try out our development build directly from our botframework-webchat package. However, without /dist folder packed, our web developers can only try out NPM package, but not bundle.

We are allowlisting:

• /dist for bundles
• /lib which exports *.js, *.d.ts, *.d.ts.map
• /src which are referenced by source map at /lib/**/*.d.ts.map

Specific Changes

• Update package.json for the following packages
  • api, bundle, component, core, and directlinespeech

• I have added tests and executed them locally
• I have updated CHANGELOG.md
• I have updated documentation
