Initial Checks

• I have searched Google & GitHub for similar requests and couldn't find anything
• I have read and followed the docs and still think this feature is missing

Description

The latest release v1.9.2 introduced changes in the configuration option copy_on_model_validation which are not reflected in the documentation.

Currently the documentation in https://pydantic-docs.helpmanual.io/usage/model_config/ shows:

copy_on_model_validation: whether inherited models used as fields should be reconstructed (copied) on validation instead of being kept untouched (default: True)
