4.9b2: sidecar posts url is not set when comming from Hashtag.get_posts()

[4bo]

Describe the bug
using Hashtag.get_posts(), when post type is Sidecar, using post.url raises this error:

app_1  |   File "/usr/local/lib/python3.9/site-packages/instaloader/structures.py", line 296, in url
app_1  |     return self._node["display_url"] if "display_url" in self._node else self._node["display_src"]
app_1  | KeyError: 'display_src'

To Reproduce

hashtag = Hashtag.from_name(client.context, name="cat")
posts = hashtag.get_posts()
for post in posts:
    print(post.url)

Expected behavior
print url!

Instaloader version
4.9b2

I am seeing that the response data from the explore/tags/{name}/ call is not providing a 'display_src' but a 'display_url' now instead. see screenshot. I am not able to fix the bug on the repo, I can just share what i see. Hope that helps

@scanansi the url property also checks display_url, but can not find it:

    return self._node["display_url"] if "display_url" in self._node else self._node["display_src"]

Thanks for trying out our beta and for reporting this bug, @4bo. You can retrieve the URLs for a sidecar post with media.display_url for media in post.get_sidecar_nodes(). Accessing post.url of a sidecar does not make any sense, since a sidecar consists of multiple media, and as such, of multiple URLs. Still, Instaloader should not produce a KeyError when accessing, rather it should return the URL of the first sidecar media, to be consistent with sidecar Post instances of other origin than Hashtag posts.
