Subject: [PATCH] conversion: accept BitNetForCausalLM architecture name
 (#25769)

Microsoft BitNet Hugging Face configs use BitNetForCausalLM while the
converter only registered BitnetForCausalLM, causing conversion to fail
with "Model BitNetForCausalLM is not supported".

Register both spellings in TEXT_MODEL_MAP and the Bitnet model class.

Fixes ggml-org/llama.cpp#25629
