Improve change-version.js (#33148)

* switch to async/await
* remove shelljs
* switch to globby; supports .gitignore out of the box
* don't write any files to the disk if they are indentical
* add two more cmd switches: --dry and --verbose
* strip leading "v" from version arguments so that we don't end up with duplicate `v`s
