Remove explicit Microsoft.SourceLink.GitHub package reference

[Copilot]

Since .NET 8 SDK, Source Link support for GitHub-hosted repositories is built into the SDK — the Microsoft.SourceLink.GitHub NuGet package is no longer needed.

Changes

• JsonExtensions/JsonExtensions.csproj — removed PackageReference for Microsoft.SourceLink.GitHub
• Directory.Packages.props — removed corresponding PackageVersion entry

Original prompt

Background

Since .NET 8 SDK, Source Link support is built directly into the SDK for GitHub-hosted repositories. It is no longer necessary to explicitly reference the Microsoft.SourceLink.GitHub NuGet package.

Task

Remove all explicit references to Microsoft.SourceLink.GitHub from the project.

In JsonExtensions/JsonExtensions.csproj, remove the following line:

<PackageReference Include="Microsoft.SourceLink.GitHub" PrivateAssets="all" />

If there is a corresponding PackageVersion entry for Microsoft.SourceLink.GitHub in Directory.Packages.props (if that file exists), remove that entry too.

Do not make any other changes. The built-in SDK Source Link support will take over automatically.
