Missing Remarks For CultureInfo About InvariantGlobalization

### Type of issue

Missing information

### Description

There is no remarks about how InvariantGlobalization impacts what CultureInfo is decided for the relevant static properties.

I could not detect the system culture set by the user through the following properties because InvariantGlobalization had been enabled by default without my acknowledgement when I created a new .NET 8 C# project in VS 2022.

```
CultureInfo.CurrentCulture
CultureInfo.CurrentUICulture
CultureInfo.InstalledUICulture
```
I only discovered InvariantGlobalization was enabled after trying to find non-invariant culture by name using `CultureInfo.GetCultureInfo`

CurrentCultures are more complex due to being per thread and changable, but I think at least InstalledUICulture needs some remarks about being overriden by InvariantGlobalization.
