Mark productVersion.txt as shipping artifact in 8.0

[Copilot]

Summary

Fixes the issue where productVersion.txt and aspnetcore-productVersion.txt were incorrectly marked as non-shipping artifacts in the ASP.NET Core 8.0 build configuration. These files are required in the final CDN locations and must be marked as shipping artifacts.

Changes

Modified eng/Publishing.props to change the ManifestArtifactData property from NonShipping=true to NonShipping=false for both:

• productVersion.txt
• aspnetcore-productVersion.txt

This ensures these version files are properly included in the shipping manifest and published to the correct CDN locations alongside other shipping artifacts.

Impact

Without this change, the productVersion.txt files would not be available in the expected CDN locations, which could impact downstream consumers that rely on these files to determine the ASP.NET Core runtime version.
