Initial Checks

• I have searched GitHub for a duplicate issue and I'm sure this is something new
• I have searched Google & StackOverflow for a solution and couldn't find anything
• I have read and followed the docs and still think this is a bug
• I am confident that the issue is with pydantic (not my code, or another library in the ecosystem like FastAPI or mypy)

Description

Pydantic uses PEP 681's dataclass_transform for compatibility with static type checkers. One of the features described in PEP 681 is the ability to describe a set of custom "field specifier" classes. In an early version of PEP 681, these were specified using a parameter named field_descriptors, but based on feedback the parameter name was changed to field_specifiers for the final version of the PEP. Pydantic is still using the (now obsolete) parameter name.

See microsoft/pyright#3912 for details.
