new_callable arg to unittest.mock.patch seems not to support partial

Bug report

Bug description:

As in the title. The following code seems to disregard the partial and proceed to call the wrapped function right away (instead of calling the wrapping partial object).

from functools import partial
from unittest.mock import patch

def wrapped():
  """an exemplary response from `some.directory.module.my_function` function"""
    return [
        {
            "some_key": "some_value",
        }]

def test_some_func():
    with patch(
        "some.directory.module.my_function", new_callable=partial(wrapped)
    ):

    # calls `my_function` internally
    some.directory.module.another_function()

Running the above will produce: TypeError: 'list' object is not callable.
Acc. to the docs an object passed as new_callable argument should be called by patch to create a new dummy object replacing the target (some.directory.module.my_function). However it seems that instead of partial being called and returning a wrapped function, a wrapped function itself is called returning the list.

CPython versions tested on:

3.11

Operating systems tested on:

macOS

从 unittest.mock.patch 入口点及其对 new_callable 的处理开始，使用报告中的 partial(wrapped) 复现用例。将观察到的调用序列与文档所述的契约进行比较，然后添加或更新回归覆盖，使 target 被预期的 callable 行为所替代。
