C# guide: possible duplication of exception-related content

The following two tutorials:

- [How to handle an exception using try/catch](https://learn.microsoft.com/en-us/dotnet/csharp/fundamentals/exceptions/how-to-handle-an-exception-using-try-catch)
- [How to execute cleanup code using finally](https://learn.microsoft.com/en-us/dotnet/csharp/fundamentals/exceptions/how-to-execute-cleanup-code-using-finally)

may be considered as duplicates of the [Exception handling](https://learn.microsoft.com/en-us/dotnet/csharp/fundamentals/exceptions/exception-handling) concept article.

@BillWagner should those tutorials be deleted and redirected to the concept article?
