Permission to Azure/azure-quickstart-templates.git denied

Hi,

Just curious about the process to upload a feature branch to create a PR. I created a template that I want to submit for a PR but I try to push my branch I get the following error:

```
remote: Permission to Azure/azure-quickstart-templates.git denied to murdockcrc.
fatal: unable to access 'https://github.com/Azure/azure-quickstart-templates.git/': The requested URL returned error: 403
```

Can someone please comment on the correct process to do this?

Start with the repository URL and the reported 403 permission error, then review the project's documented contribution workflow for submitting a feature branch. Done means the correct fork-and-pull-request process is clearly documented or confirmed for contributors.
