Add job to publish artifacts to NuGet in GithubActions.yml

Added a new job "Publish Build Artifacts to NuGet Feed" in GithubActions.yml. This job, running on a PowerShell shell, pushes the build artifacts (.nupkg files) to a NuGet feed using the `dotnet nuget push` command. The API key and source are fetched from GitHub secrets and variables respectively. This change enables distribution of build artifacts to users via the NuGet package manager.
