Build/Test Tools: Revert uglify-js update.

This partially reverts [58563], which applied an update of the `uglify-js` `devDependency` from `3.17.4` to `3.18.0`.

The `3.18.0` update is causing some JavaScript errors in the `media-views.min.js` file, so needs to be investigated further.

Fies #61519.
