Add an `rit uninstall` core command

[GuillaumeFalourd]

What would you like to be added:

• A core command to make it easy to uninstall Ritchie CLI.

Why is this needed:

• Following different guidelines, we need a CLI easy to uninstall.

If it needs instructions, put them at the bottom of the install instructions—one of the most common times people want to uninstall software is right after installing it.
