handle commiting when no file change

[Lee-W]

In cz-cli, if we run git cz without any file change, we'll get the message "No files added to staging! Did you forget to run git add?".

However, in cz c, we can still run the whole process.
The git commit is not actually created.

Maybe we can detect file change like cz-cli? Or, at least we could let the user know that this commit is not actually created.

I like the idea. I'm not sure whether we should do it before or after the prompted questions. What would you suggest?

I would suggest do it before because in such situation all the actions after that are meaningless.

Agreed, I had that very same issues a few minutes ago haha. Feel free to create a PR to fix this.
