fix(azure/gpt-5): restore 'user' param after azure/ normalization

Browse source 
OpenAIGPTConfig.get_supported_openai_params only adds 'user' when the
model is found in litellm.open_ai_chat_completion_models. Normalizing
the model to 'azure/<name>' for capability lookups caused that check
to miss, dropping 'user' from the supported params list for Azure GPT-5
models. Add it back explicitly, mirroring the existing tool_choice fix.
