chore: order csproj ItemGroups for inclusion

[wlsnmrk]

Placed the production-dependencies ItemGroup above the test-dependencies ItemGroup in the game csproj. Now when users execute dotnet add package, the new package will by default be added to the production-dependencies group. This avoids placing production dependencies in a group that is compiled out in non-test builds, which causes unforeseen build errors when building without tests.
