Removed [A]ll - yes to all

[LemonjamesD]

Description Of Changes

Changed the prompt of Do you want to run thin script?([Y]es/[A]ll - yes to all/[N]o/[P]rint) to Do you want to run thin script?([Y]es/[A]ll/[N]o/[P]rint)

Motivation and Context

Unnecessary info as the command line app should assume the user knows what [A]ll, and this feature already exists for every other modern package manager on linux.
