CBT2.0.2 Add Lua converters for thread-safe and immutable collections

Implemented custom Lua converters for various thread-safe lists, ImmutableList, ImmutableHashSet, and ImmutableDictionary types. This allows seamless conversion between C# collections and Lua tables, improving Lua scripting integration with these collection types.
