Add new remote option when publishing branch

[jmbockhorst]

Added the ability to add a new remote when publishing a branch. Closes #71242. Here is an example of creating a new branch, selecting the publish branch command, and creating a new remote. The branch gets published to that new remote.

I had a few questions about some ways to make the remote experience more consistent:

• Should the ability to add a remote be an option on the "Push to.." and "Pull from..." menus as well?
  

• Should the remotes on the "Publish branch" command show the remote URL, like the "Push to.." and "Pull from..." menus do?

I think "if" statement can be inverted.

if (!newRemote) {
    return;
}
     
remote = newRemote;

Thanks! 🍻

I've added this to the Push to... command as well, since it was pretty straightforward. I've also added the URL to the option description in quick pick.

Great. Now I have to pick origin every time I publish? If you only have one remote, there is no reason to prompt for a publish. Guess I'll go back to using the terminal and git push -u. :-(

@rkeithhill I already reverted this in master.
