FastAPI 0.155.0 removes deprecated **extra request-parameter arguments

The October 21 Korean-date stable release and PyPI distribution were verified. Deprecated **extra keyword arguments were removed from Path, Query, Header, Cookie, Body, Form, and File; unknown arguments now raise TypeError. Move additional JSON Schema properties from Query(custom="value") to Query(json_schema_extra={"custom": "value"}), for example. Check custom arguments and related validation tests before upgrading.
