CA2219 (Do not use throw in finally) documentation should suggest alternative approaches

### Type of issue

Missing information

### Description

The article on [CA2219: Do not raise exceptions in exception clauses](https://learn.microsoft.com/en-us/dotnet/fundamentals/code-analysis/quality-rules/ca2219) currently (as of 2025-09-03) provides only a dogmatic "you should never do this" statement but does not suggest any alternative approaches to resolve the CA warning:

------

I quote (emphasis mine):

> ## How to fix violations
> To fix this violation of this rule, do not explicitly raise an exception from a finally, filter, or fault clause.
>
> ## When to suppress warnings
> Do not suppress a warning for this rule. **There are no scenarios under which an exception raised in an exception clause** provides a benefit to the executing code.

-------

Its easy to trigger CA2219 warnings when working with COM or PInvoke in C#, where our `finally` or `void Dispose` methods call into native methods that can/will/do fail with exceptions or runtime errors of their own; this includes C# code generated by [CsWin32](https://github.com/microsoft/CsWin32), for example.

-----

Normally I'd provide some text to be copied+pasted into the article, but such-as-it-is, I don't know what the current Best Practices advice is for "failable-finally" clauses. I did find [this related feedback suggesting passing exceptions around in locals](https://github.com/dotnet/roslyn-analyzers/issues/5869#issuecomment-2459837482) - but it offends my aesthetics. In my own software I've stopped trying to faff-around with second-order exceptions and simply call `Environment.FailFast` in event of an (unexpected) second-order exception, but I'm sure a better approach must exist.
