Fix Process.parse_argument behavior against a quote in a word

[makenowjust]

Fixed #10306
Thanks, @erdnaxeli for reporting.

It fixes the condition to an end of a bare word on a quote character.

Now, it works as we expected.

require "process"

pp ARGV
pp Process.parse_arguments(%(this 'is a "'very wei"rd co"m"mand please" don't do t'h'a't p"leas"e))

$ bin/crystal run a.cr -- this 'is a "'very wei"rd co"m"mand please" don't do t'h'a't p"leas"e
["this", "is a \"very", "weird command please", "dont do that", "please"]
["this", "is a \"very", "weird command please", "dont do that", "please"]

Too bad it wasn't merged for 0.36.1. I guess I will keep my lib for now :)
