Pull request overview

Updates the CS0465 compiler warning documentation to better reflect current compiler behavior and to point readers to the C# finalizer/destructor guidance.

Changes:

• Updates the article metadata (ms.date) and adds ai-usage frontmatter.
• Revises the warning explanation to avoid overstating a specific accessibility modifier and links to the C# finalizers documentation.
• Minor wording/formatting adjustments around the example lead-in.

• The article mixes terminology (“destructor invocation” in the warning text vs “finalizer invocation” in the explanation). Consider using one term consistently, or explicitly clarify that C# destructors map to finalizers, to avoid confusion for readers.

A method named `Finalize` can interfere with finalizer invocation. To define a finalizer, declare `~TypeName()` instead of a `Finalize` method. For more information, see [Finalizers](../../programming-guide/classes-and-structs/finalizers.md).
