Confusing "implement a Close method"

### Describe the issue or suggestion

On the [Object.Finalize](https://learn.microsoft.com/en-us/dotnet/api/system.object.finalize?view=net-10.0) page. The "How finalization works" section mentions `Close`, capitalized and in a code format. If I understand correctly, from the Essential C# book. A close function means any method that manually frees resources. This is not a special type of method, a language feature. Merely suggested style (whether that is strictly enforced like PowerShell verbs, or not).

As this is a significant part of .NET, making it clear what is meant here could be improved. As is, the very verbose writing style without any further explanation, makes it seem like something it is not?

Open xml/System/Object.xml and locate the Object.Finalize content for the "How finalization works" section. Read the surrounding explanation and clarify what "Close" means, distinguishing it from a special method or language feature; done means the section no longer suggests that Close has special .NET semantics.
