[iOS] Using CompareOptions.IgnoreSymbols throws an exception in .net 9

[claytonone]

Description

Attempting to call CultureInfo.InvariantCulture.CompareInfo.IndexOf with CompareOptions.IgnoreSymbols throws a PlatformNotSupportedException (see log output below for full message) on iOS but works fine for Android. This used to work fine in .net 8 MAUI.

CultureInfo.InvariantCulture.CompareInfo.IndexOf("string 1", "strng 2", CompareOptions.IgnoreSymbols) >= 0;

The exception talks about disabling HybridGlobalization but I cannot find any documentation about this for MAUI.

Steps to Reproduce

1. Attempt to call CultureInfo.InvariantCulture.CompareInfo.IndexOf with CompareOptions.IgnoreSymbols
2. Note that it throws an exception on iOS
