Pull request overview

This PR systematically removes references to the now-obsolete Try.NET interactive code runner from the .NET documentation. The changes clean up outdated interactive features and update links to reflect the current state of available learning resources.

Key changes:

• Removed csharp-interactive code fence attributes and replaced them with standard csharp throughout multiple files
• Deleted the csharp-interactive-with-utc-note.md include file that explained Try.NET behavior
• Updated tutorial links to point to current learning resources (GitHub Codespaces-based tutorials instead of Try.NET)
• Fixed various formatting issues including table alignment, trailing spaces, and comment punctuation
