[Feature request] Add a feature to blank out the default description

[cvanelteren]

First of all, thanks for the extension I like the core idea. However during use I find myself having to do "too much work" to remove the default parameter description, I therefore propose to add an option to leave the link blank after the parameter type "Description of variable `whatever'". Specifically change:

def f(x = None) -> None:
    """Short summary.

    :param x: Description of parameter `x`. Defaults to None.
    :return: Description of returned object.

    """
    return x

To:

def f(x = None) -> None:
    """Short summary.

    :param x: . Defaults to None.
    :return:

    """
    return x

Edit: I tried playing around with the source js script but for some reason, it doesn't stick, I'll look at it later as well.

Sure. Sounds like a reasonable idea. I don't have much time the following weeks (conference) but I can review and potentially merge a PR.
