Getting episodes no longer works.

[Erotemic]

Issue description

It looks like there has been a change that prevents getting epsidoe information from working. A few weeks ago it was working, but now the same calls result in 0 discovered episodes.

Version of Cinemagoer, Python and OS

In [8]: imdb.__version__
Out[8]: '2023.05.01'
In [12]: sys.version_info
Out[12]: sys.version_info(major=3, minor=11, micro=2, releaselevel='final', serial=0)

Steps to reproduce the issue

if possible, provide a minimal code to reproduce the problem

    from imdb import Cinemagoer
    imdb_id = '0131664'
    ia = Cinemagoer()
    print('Submit IMDB query')
    imdb_item = ia.get_movie(imdb_id, info=['main', 'episodes'])
    print(imdb_item.get('number of episodes'))  # prints 0
    print(imdb_item.get('episodes'))  # prints None

I don't have the expected result, but I know this query was working in December 2023. I think the external episode information layout has changed. I did attempt to look into it a fix, but it looks like it isn't a simple thing.

#503 should fix
