(🐞) error code that is enabled in the config file can't be disabled on the CLI (with `--disable-error-code`)

I think it would be intuitive for commandline arguments to override config file options, but the way that enable/disable-error-code works isn't.

pyproject.toml

[tool.mypy]
enable_error_code = "operator"

> mypy --disable-error-code operator -c "1 + ''"
test.py:1: error: Unsupported operand types for + ("int" and "str")  [operator]
Found 1 error in 1 file (checked 1 source file)

The docs specify how these flags interact with themselves, but don't mention the ones in the config file.

--enable-error-code
This flag allows enabling one or multiple error codes globally. See [Error codes](https://mypy.readthedocs.io/en/stable/error_codes.html#error-codes) for more information.

Note: This flag will override disabled error codes from the [--disable-error-code](https://mypy.readthedocs.io/en/stable/command_line.html#cmdoption-mypy-disable-error-code) flag.

首先追踪 mypy 如何将 pyproject.toml 中的 enable_error_code 和 disable_error_code 与命令行选项结合起来。使用 --disable-error-code operator 重现该示例，然后为配置与 CLI 的组合添加覆盖测试。当 CLI 选项能够抑制已配置的错误代码，并且文档解释了这一优先级时，即表示完成。
