Break up build and NuGet publish to separate sections

- Introducing a separate job dedicated to NuGet publishing, triggered only for tagged builds.
- Uploading the NuGet package as an artifact in the build job.
- Downloading the artifact in the publish job.
- Corrects the path to the NuGet package in the push command, using the output version from the build job.
