Adopt GitHub Auth provider for issues reporter

[RMacfarlane]

Since we now have a way for users to login to GitHub within VSCode, we can leverage this in the issue reporter. As a first step, if the user is already signed in and we have a token with scopes for creating an issue, we can just directly post the issue instead of showing the intermediate "new issue" page

Point to note: users may have one set of credentials that they work against, but may want to report issues under a different set of credentials. (e.g. work vs personal).

Could the UI promote this solution so the (imo hacky) copy&paste is avoided?
The issue report screen could be broken into two workflows (if not connected):

• "Connect with GitHub to report an issue" button (opens form after signin, works without copy&paste)
• "Open GitHub in your browser" (opens issue template directly in GitHub, avoids form entirely)

And if connected, it would just show the form directly.

Any updates on this?
