Retry git push when remote ref is ahead

[mubarak-j]

I'd like to update this push function to handle the error when the remote ref is ahead of current repo copy.

func (m *nativeGitClient) Push(remote string, branch string, force bool) error {
	args := []string{"push"}
	if force {
		args = append(args, "-f")
	}
	args = append(args, remote, branch)
	err := m.runCredentialedCmd("git", args...)
	if err != nil {
		return fmt.Errorf("could not push %s to %s: %v", branch, remote, err)
	}
	return nil
}

I'd like to catch this error and retry by running git pull before running git pull again.
I'm trying to fix a bug in an upstream project but I'm not familiar with Golang. I'm hoping someone can point me to an example implementation 🙏🏼
