TypeError: expected str, bytes or os.PathLike object, not NoneType

I use browser_cookie3 in one of my projects, and a user reported this crash to me on Python 3.12 on Ubuntu 24.04 using browser_cookie3==0.20.1:

 File ".../lib/python3.12/site-packages/browser_cookie3/__init__.py", line 445, in __init__
    self.__add_key_and_cookie_file(**kwargs)

    cookie_file = self.cookie_file or _expand_paths(

TypeError: expected str, bytes or os.PathLike object, not NoneType

I haven't gone through the motions of reproducing this, but from reading the code, I think the issue could be that the Arc class doesn't define linux_cookies like the other ChromiumBased subclasses do: https://github.com/borisbabic/browser_cookie3/blob/master/browser_cookie3/__init__.py#L695. Therefore linux_cookies=None gets passed to the _expand_paths(linux_cookies, 'linux') function call on https://github.com/borisbabic/browser_cookie3/blob/master/browser_cookie3/__init__.py#L473.

In my code, I'm just calling browser_cookie3.load(domain_name) instead of specifying a browser.

I am seeing the same error, using Python 3.10.13, Linux Mint 21.3, browser_cookie3==0.20.1.

The error happens when calling browser_cookie3.load(domain_name).

When I switch to specifying the browser, it works OK: browser_cookie3.firefox(domain_name).
