NET 8 Upgrade (#687)

* Initial .NET8 Upgrade

* Initial GitHub Actions Cleanup

* Fix Desktop Notifications

* Fix throw warning

* Upgrade vunerable transative nuget packages

* Fix warnings with registry overflow

* Adjust async/await usage for configRepository

* Fix TTS voice name and app auto start

* Install .NET 8 with setup

I regret NSIS

* Remove no longer needed System/MS references (included in dotnet sdk)

* Surpress stackalloc in loop warning, that code scares me.

* Removed unused SharpDX packages

* Ignore WebClient warning, hopefully this project doesn't move past NET 8

* Fixed terrifying code

* GenerateAssemblyInfo

* Trimmed editor config to only silence warning.

* Fix open webpage

* Fix updater
