Dependabot / NETSDK1047 - Nuget packages no longer updating

Dependabot is broken since a few months for nuget packaged. It was working in the past.

```
Error msg:

Build FAILED.

/usr/local/dotnet/current/sdk/8.0.414/Sdks/Microsoft.NET.Sdk/targets/Microsoft.NET.Sdk.targets(284,5): error NETSDK1047: Assets file '/home/dependabot/dependabot-updater/repo/Source/NETworkManager.Profiles/obj/project.assets.json' doesn't have a target for 'net8.0-windows10.0.22621/win-x64'. Ensure that restore has run and that you have included 'net8.0-windows10.0.22621' in the TargetFrameworks for your project. You may also need to include 'win-x64' in your project's RuntimeIdentifiers. [/home/dependabot/dependabot-updater/repo/Source/NETworkManager.Profiles/NETworkManager.Profiles.csproj]

Start with Source/NETworkManager.Profiles/NETworkManager.Profiles.csproj and reproduce the reported Dependabot build failure involving net8.0-windows10.0.22621/win-x64. Trace the restore inputs that produce project.assets.json; done means the Dependabot update build completes without NETSDK1047.
