NamedTuple single line declaration gives error "Too many arguments for NamedTuple() [misc]

Bug Report

typing.NamedTuple one line declaration gives incorrect error

To Reproduce

# test.py
from typing import NamedTuple

ExampleClass = NamedTuple('ExampleClass', test_id=str, timestamp=str)

mypy --show-error-codes test.py

test.py:[line-no]: error: Too many arguments for NamedTuple()  [misc]

Expected Behavior

mypy doesn't give this error

given the above syntax is valid python and works fine, I would expect it to not throw an error, like the following old structure declaration does not, which is labeled as "back-ward compatible usage" in the official doc

ExampleClass = NamedTuple('ExampleClass', [(test_id, str), (timestamp, str)])

Actual Behavior

error: Too many arguments for NamedTuple()  [misc]

Your Environment

mypy --version
mypy 0.910

python --version
3.8.10

首先使用 mypy --show-error-codes 运行报告中的 test.py 示例，并检查 NamedTuple 调用处理。完成的标准是：基于关键字的单行声明不再错误地产生 "Too many arguments for NamedTuple()" 错误，同时现有的基于列表的声明仍能被接受；如果确定了 repository 中测试的位置，请添加回归测试。
