Update NuGet restore command and modify project references

Changed the NuGet restore command in `build.yml` to include the property `/p:BuildWithNetFrameworkHostedCompiler=true` for better compatibility. Removed the `<PackageReference>` for `Microsoft.Net.Sdk.Compilers.Toolset` in `openHAB.Common.csproj`, which may impact the build process.
