[Quality Of Life] Use 'package_info_plus' to update version number in settings

[Ranger-NF]

I noticed that you were changing the version number manually on every update. You could use package_info_plus to do that for you. As of right now, there is only a single place where the version number is shown, so its up to you if you want to use it or not :)

Agreed, I plan to automate the version codes in all the files at some point.
