Fixed #7027 - Use a maintained library to minify JS

[Dillon-Brown]

Description

Part of my ongoing efforts to remove manually included libraries and replace them with composer packages. This PR replaces the outdated tedious/JShrink and instead loads an updated version with composer. I've also re-minified the existing JS files using the updated library.

Motivation and Context

Issue reference: #7027

How To Test This

1. Run JS repairs in admin panel.
2. Check that minified JS works as expected.
