Remove compiled / minified source code from Git

[RA80533]

Minified content is assumed to be ready for consumption due to its association with post-processing workflows. The minified files in the repository are not actually ready for consumption in certain browsers due to the use of Node.js-specific features such as require. This isn't very apparent because the files are minified.

Minification is typically the last step in post-processing workflows, occurring prior to content deployment via npm or some other medium (e.g., CDNs).
