Remove deprecated Thread.Abort from "Pausing and interrupting threads"

[Copilot]

• Create new C# snippet in snippets/pausing-and-resuming-threads/csharp/ showing only Thread.Interrupt (no Thread.Abort)
• Create new VB snippet in snippets/pausing-and-resuming-threads/vb/ with the same change
• Update pausing-and-resuming-threads.md to remove Thread.Abort references from prose and bullet points
• Update article snippet references from legacy [!code-...] to modern :::code::: format
• Remove ThreadAbortException from See Also section; added link to cooperative cancellation article
• Delete old legacy snippet files (only referenced in this article)
• Verified C# and VB snippets compile successfully (net10.0)
• Verified C# example produces correct output
• Add sentence after code example describing what Thread.Join does

@copilot can you add a sentence describing what the Thread.Join method does: https://review.learn.microsoft.com/dotnet/api/system.threading.thread.join?view=net-10.0&branch=main in the Thread.Sleep method section.

Added a sentence after the code example (commit a264e20): "The example calls Thread.Join to block the calling thread until the interrupted thread finishes execution."
