Updated all projects to target .NET 10.0, removing support for .NET 6.0. Upgraded key dependencies, including:
- `Microsoft.Build` and `Microsoft.Build.Tasks.Core` to 18.0.2.
- `Nuke.Common` to 10.1.0.
- `System.Drawing.Common` to 10.0.1.
- `System.Text.Json` to 10.0.1.
Removed `NoWarn` configurations for .NET 6.0 in `ElectronNET.AspNet.csproj`. Reformatted the `Copy` task in `ElectronNET.Build.csproj` for readability. Updated `.pubxml` files and other project files to reflect the framework upgrade.
