Improve Images

[SuperSandro2000]

Right now the images don't use any kind of templating I could find cause otherwise I would have done a PR to fix all those issues:

• apt cache is not getting deleted and apt-get update does not run in the same layer as apt-get install which is against dockers best practices and can lead to caching issues where you never install never packages
• chromedriver.zip does not get deleted and shipped in the final image which unnecessarily increases image size
• The script just installs any latest version of Chrome and is not reproducible
• download mirrors are hard coded
• older alpine versions are used instead of the latest
• you run apk update which is not necessary and apk add should be run with --no-cache

What would it take to add templating so that you could do this?
