Describe the feature or problem you’d like to solve

If you run gh repo create in a folder that isn't initialized with git the command fails.

Proposed solution

Instead of failing the user would be asked if they want to initialize the current folder a git repo.

Additional context

I would love to take up the implementation of this! The go-git module seems like the easiest way to implement this but it is a big dep. Should we just run an exec command or is there some other way to do it?

p.s. thank you for making this awesome cli :)
