github-release: create the Discussion separately

When deploying v2.46.1, trying to publish the release _and_ creating the
discussion failed like this:

	FAILED GitHub REST API call!
	{
	  port: 443,
	  hostname: 'api.github.com',
	  method: 'PATCH',
	  path: '/repos/git-for-windows/git/releases/175612508',
	  headers: {
	    'User-Agent': 'GitForWindowsHelperApp/0.0',
	    Accept: 'application/json',
	{
	  statusCode: 404,
	  statusMessage: 'Not Found',
	  body: '{"message":"Discussion could not be created. Make sure you passed a valid category name.","documentation_url":"https://docs.github.com/rest/releases/releases#update-a-release","status":"404"}',
	  json: {
	    message: 'Discussion could not be created. Make sure you passed a valid category name.',
	    documentation_url: 'https://docs.github.com/rest/releases/releases#update-a-release',
	    status: '404'
	  }
	}
	    Authorization: '***',
	    'Content-Type': 'application/json',
	    'Content-Length': 96
	  }
	}

Culprit: The GitForWindowsHelper GitHub App, with whose permissions this
was run, lacked the permission to create Discussions.

The release was published, though...

So let's separate those two steps, publishing a draft release, and
adding the discussion, and do not fail the deployment if the Discussion
could not be created.
