Replace .npmignores with the file field

[sdadn]

Summary

This PR replaces .npmignore files with the files prop to denote what files will be published. The .npmignore works by blacklisting files, while files works by whitelisting files to be published. This change was made as it is more convenient to keep track of files that need to be published than finding potential files that don't need to be published. It also results in fewer issues when running npm pack locally.

Testing

This change was tested using:

• WDIO
• Jest
• Visual testing (please attach a screenshot or recording)
• Other (please describe below)
• No tests are needed
