NuGet package license URL has changed the meaning

[lg2de]

There are several NuGet packages (e.g. System.Buffers 4.3.0) on nuget.org that use the URL http://go.microsoft.com/fwlink/?LinkId=329770 as license information.
At the time these packages were released, the URL was redirected to https://dotnet.microsoft.com/dotnet_library_license.htm.
This means that these packages are licensed under the "MICROSOFT SOFTWARE LICENSE TERMS" "MICROSOFT .NET LIBRARY".

According to archive.org, the redirect was changed to https://github.com/dotnet/core/blob/main/license-information.md on September 12, 2024. (This document was created and updated with #9069 and #9440.)
The new documentation states: "This document is provided for informative purposes only and is not itself a license."

So, old packages no longer have valid license information.
