Documentation for instance variables without docstrings

I'm a bit surprised that instance variables aren't automatically picked up if they don't have docstrings. Property methods without docstrings are listed, I'd expect regular instance variables to show up as well.

Expected Behavior

class Test:

    one: str
    two: str

    def __init__(self, value: str) -> None:
        self.one = value
        """one docstring."""
        self.two = value

    @property
    def foo(self) -> str:
        return self.value

    def bar(self) -> int:
        pass

should become:

Classes
-------

`Test(value: str)`
:   

    ### Instance variables

    `foo`
    :

    `one`
    :   one docstring.

    `two`
    :

    ### Methods

    `bar(self) -> int`
    :

(I actually expect the types to show as well for all three instance variables, but that's covered in #121.)

Actual Behavior

Classes
-------

`Test(value: str)`
:   

    ### Instance variables

    `foo`
    :

    `one`
    :   one docstring.

    ### Methods

    `bar(self) -> int`
    :

Steps to Reproduce

See sample code above.

Additional info

• pdoc version: 0.7.4

Start with the sample Test class and compare the generated documentation with the expected output. Trace how pdoc discovers instance variables and update that behavior so undocumented variables such as two are listed, then verify the output against the example and preserve the existing one docstring and property entries.
