I've put up a pull request to add @BreD1810! 🎉

I'm not really sure where to go from here :/. I've had a look at the way the GitHub CLI implements executing aliases. Unfortunately, I am quite new to Golang, and very new to cobra, so I haven't managed to work it out yet.
Any suggestions are appreciated!

I've been following your commits and I can say you started out really well.
We can save the aliases in a separate file (aliases.format) in the global config directory and map the aliased command to its corresponding key value.

Great implementation @BreD1810
Works as expected 🎉

I will write unit tests for it
