Pin pydantic==2.10.6 to fix gradio_client schema bool TypeError

Per HF forum (discuss.huggingface.co/t/154601), newer pydantic emits
'additionalProperties: True' schemas that gradio 4.44.1's bundled
gradio_client 1.3.0 crashes on. Pinning pydantic to the last
gradio-compatible release fixes it at the source. Removing the
in-app monkey patch since the upstream pin is enough.
