Update Netherite publish.yml NuGet release step

[bachuv]

This pull request updates the NuGet publishing process in the CI pipeline to publish multiple packages separately, improves maintainability, and switches to a newer, more robust publishing task. The previous single-job approach is replaced with three distinct jobs, each targeting a specific package, and the legacy DotNetCoreCLI@2 task is replaced with the 1ES.PublishNuget@1 task for better integration and validation.

NuGet publishing pipeline improvements:

• Replaced the single nugetRelease job with three dedicated jobs for publishing Microsoft.Azure.DurableTask.Netherite, Microsoft.Azure.DurableTask.Netherite.AzureFunctions, and Microsoft.Azure.Functions.Worker.Extensions.DurableTask.Netherite NuGet packages, allowing for more granular control and easier troubleshooting.
• Switched from the DotNetCoreCLI@2 task to the 1ES.PublishNuget@1 task for pushing packages to NuGet, which provides better support for skipping duplicates and improved SDL tooling integration.
• Updated the job configurations to ensure each job only publishes its intended package and excludes symbol packages and unrelated artifacts, improving reliability and compliance.
