fix(package.json): update main and module file paths

[SteKoe]

What:
Updated main and module paths in package.json

Why:
I got the following error after upgrading to 6.1.0 in my project:

SyntaxError: Named export 'parse' not found. The requested module '@adobe/css-tools' is a CommonJS module, which may not support all module.exports as named exports.
CommonJS modules can always be imported via the default export, for example using:

import pkg from '@adobe/css-tools';
const { parse } = pkg;

After updating the paths in package.json and testing using npm link locally, everything works as expected, again.

How:
