reorder cli commands to be alphabetic ordered

[beanieboi]

hey all!

i had a hard time finding options in excercism --help this PR just reorders them alphabetically. for me personally this makes it way easier to skim the options and find the option i want.

i would no way to change the position of help it's at the end of the command list. which is fine for me.

this is how it looks like on my machine after the change.

I think this is a great idea. I actually thought (but never verified) that it was ordered alphabetically by default. /shrug :)
