Feature/Enhancement Request | Remove the "No upstream branch found" message from the `git status` subcommand

[JosephLai241]

Provide Context for the New Feature or Enhancement You Would Like

I recently learned some people do not run git push --set-upstream origin <BRANCH_NAME> when pushing code from a new branch upstream. nomad currently assumes a user would do this, and displays the number of commits ahead of an upstream branch assuming the user has ran that Git command.

A message "No upstream branch found" is displayed if the user does not run that Git command and runs the nd git status subcommand.

Explain Why You Believe This Would Be a Good Feature

The "No upstream branch found" message may become annoying for anyone who does not run that Git command to set the upstream branch. I think I should remove this message and only display the number of commits ahead if the user chooses to set the upstream branch.
