.azure-pipelines/release.yml: add GitHub and NuGet.org publishing

Add a new stage (after build) to publish the assets to GitHub and
NuGet.org.

Each target (GitHub and NuGet.org) need to run in separate jobs
due to restrictions of the 1ES pipeline templates:

- Publishing a NuGet package requires us to use template `outputs`
- `type: releaseJob` cannot specify outputs
- `type: releaseJob` is required to use the `GitHubRelease` task
