feat: Update SDK page to use single NuGet templates package

Changed from two separate tar.gz download links to a single NuGet package:
- Updated Quick Start to use 'dotnet new install SilverLabs.SilverSHELL.Templates'
- Replaced dual download cards with single templates package card
- Link now points to https://nuget.silverlabs.uk/packages/silverlabs.silvershell.templates/
- Simplified installation process for users
