Add runtime_dependencies.json for C# language server

Creates consistent configuration structure with other language servers:
- Extracts hardcoded URLs/versions to JSON configuration
- Supports both .NET runtime and language server packages
- Maintains platform-specific package handling
- Keeps NuGet source configuration centralized

This improves maintainability and follows the established pattern
used by all other language server implementations.
