Several unnecessary files are being output into the NPM package.

Several config files are being unnecessarily added to the npm package:

• babel.config.js
• eslint.config.js
• jest.setup.js
• tsconfig.eslint.json

Also some generated test and storybook files:

• /.../{component-name}.test.d.ts
• /.../{component-name}.stories.d.ts

There may be other files we can ignore too.
