fix(converter): add Boolean2StrConverter alias class and resource key (closes #243)

[omid-io]

Summary

Fixes #243 where referencing Boolean2StrConverter (as documented in the documentation) fails because only Boolean2StringConverter was defined as the class name and resource key.

Root Cause

The file is named Boolean2StrConverter.cs, and the official documentation specifies Boolean2StrConverter with [str0];[str1] parameter formatting, but the class declared in Boolean2StrConverter.cs is Boolean2StringConverter. Consequently, developers following the documentation who reference Boolean2StrConverter in XAML receive a missing resource / type error.

Solution

1. Added a backward-compatible alias class Boolean2StrConverter inheriting from Boolean2StringConverter in src/Shared/HandyControl_Shared/Tools/Converter/Boolean2StrConverter.cs:

   public class Boolean2StrConverter : Boolean2StringConverter
   {
   }

2. Added the corresponding resource entries:
   • <converter:Boolean2StrConverter x:Key="Boolean2StrConverter"/> in Converters.xaml and Theme.xaml (Shared and Net_40).
   • Added token Boolean2StrConverter in ResourceToken.cs.

Verification

• Built src/Net_GE45/HandyControl_Net_GE45/HandyControl_Net_GE45.csproj with target framework net8.0-windows (0 errors, 0 warnings).
• Built src/Net_GE45/HandyControlDemo_Net_GE45/HandyControlDemo_Net_GE45.csproj with target framework net8.0-windows (0 errors, 0 warnings).
