Move jquery-minicolors to npm/webpack (#12305)

* Move jquery-minicolors to npm/webpack

- Unvendor and add as npm dependency
- Removed unneeded backend variable
- Fixed existing bug where picker would previously initizalize to the
  same green color when editing a label.

There was probably a version bump because the previous version was
over 3 years old but it seems to be compatible.

* use file-loader

* trailing comma and comment update

* misc tweaks
