Electron: 17.2.0

OS: Darwin x64 20.5.0

Steps to Reproduce:

1. Just push a commit to a repo that user don't have permission
2. A message modal will show to ask user if they want to create a fork repo
3. Click close button
4. VSCode create a fork for you
5. But user don't want to creat a fork, that's why they close it.

I check the code, looks like github extention only check no to return.

What I suggest

	if (answer !== yes) {
		return;
	}

If you think this were resonable, I will make a PR for it
