Fix Composer 2.0 issue for bower-asset/jqueryui-touch-punch library default branch

Problem/Motivation

Reported by J.Edgar

I was getting a warning saying jquery_ui_touch_punch was missing. I added it to my composer file as a requirement and it removed the issue. Was this removed by mistake?

Steps to reproduce

Composer 2 is not taking the dev-master by default from bower-asset

"bower-asset/jqueryui-touch-punch": "*",

Instead, it's getting the gh-pages branch

https://github.com/furf/jquery-ui-touch-punch/tree/gh-pages

Proposed resolution

To work in Compose 2 it should be changed to

"bower-asset/jqueryui-touch-punch": "dev-master",

to get
https://github.com/furf/jquery-ui-touch-punch/tree/master
In composer 1: the default was the master branch
In composer 2: it's alphabetical for the * require selection option

Remaining tasks

• Change bower-asset/jqueryui-touch-punch to dev-master in composer.json
• Test build and update of Varbase 8 + Varbase 9
• Test with composer 1.0
• Test with composer 2.0
• Update the documentation
  Updating Varbase to work with Composer 2.0
• Release Varbase 8.8.9 and Varbase 9.0.0-rc2
