LibCore: Add --version flag to ArgsParser

Browse source 
`--version` always prints "git" for now.

The motivation is that the neofetch port calls `Shell --version` and
adds the output to its output. And if `Shell --version` prints a long
error message about it not knowing the flag, neofetch's output looks a
bit ugly. Per Discord discussion, just add the flag to ArgsParser
instead of only to Shell.
