title: How do I change the GitHub URL in Visual Studio?
body: <p>I know this is probably a really dumb question, but I can't figure it out. 
  When you go to your branches, right click on one, and click publish, the first time it asks you for a URL and I put in the wrong one (one that doesn't even exist haha). So now whenever I try to publish a branch, it says it can't find it and I don't know how to change the URL because the option doesn't come up anymore.</p>
