System.Diagnostics.PerformanceCounterType.NumberOfItems32 got wrong description

https://docs.microsoft.com/en-us/dotnet/api/system.diagnostics.performancecountertype?view=net-5.0 shows `NumberOfItems32`:

```
An instantaneous counter that shows the most recently observed value. Used, for example, to maintain a simple count of items or operations. Counters of this type include Memory\Available Bytes.
```

which is not true, In my test:
```
> (new PerformanceCounter("Memory", "Available Bytes", true)).CounterType
NumberOfItems64
```
