It's a little late for my liking to update this in 5.7, especially while also continuing down the jQuery update roadmap, but let's get this in 5.8.

Looking through the release details, it appears that they are also releasing the library to NPM again. We should change package.json back to using NPM instead of downloading from GitHub.

In 50543:

External Libraries: Update jQuery Color library to version 2.2.0.

This updates the jquery-color library from version 2.1.2 to 2.2.0.

This also switches back to installing the dependency from NPM instead of GitHub. The maintainers have resumed publishing to NPM with the 2.2.0 release.

A full list of changes can be found on GitHub: ​https://github.com/jquery/jquery-color/compare/2.1.2...2.2.0.

Props hareesh-pillai, desrosj.
Fixes #51405.

External libraries: Update jQuery Color to 2.2.0

The NPM package for jQuery Color was updated in [50543], but a bundled version still existed within core.
This removes that bundled version, in favor of expanding the Grunt build steps to include the package from NPM instead.

Fixes #55016. See #51405.
