Confusing terminology in SafeHandle example code

### Describe the issue or suggestion

As this is a part of .NET that is very basic, for new programmers to understand. The wording:
> this SafeHandle instance "owns" the handle

seems clumsy. It would be more clear if it instead doesn't conflate instantiation with implementation. Something like:
> informing the base class that the instance of this SafeHandle implementation "owns" the handle

https://learn.microsoft.com/en-us/dotnet/api/system.runtime.interopservices.safehandle?view=net-10.0

Open the linked SafeHandle API reference page and locate the example wording that says the SafeHandle instance "owns" the handle. Revise the wording to clarify that the SafeHandle implementation informs its base class that it owns the handle, then verify the page reads clearly for new programmers.
