feat: upgrade dependencies and remove unnecessary dependencies

[felixranesberger]

This pull request changes quite a few things.
The main goal was to upgrade glob from v7 to a newer version, since all versions below v9 throw an warning on install that the version is outdated.

While doing that I also upgraded and changed a few things:

• Upgraded glob version in kss-scheibo
• Depend on new version of scheibo kss-node fork that removes bluebird and updates fs-extra and glob
  see: feat: upgrade glob from v7 to v11 kss-node#2
• Removed bluebird since glob and fs-extra now fully support promises.
• Upgraded browser-sync since the old version depends on old glob version
• Removed eslint, since it wasn't really used or working anyway
• Removed jshint since it was quite old, the rules outdated and used legacy glob as a dependency
• Upgraded browser-sync as it depended on old glob version

When creating a new test styleguide using the new changes, I got the same results and no errors, so everything should work as expected.
