Unhandled exception if the IA response is a HTML 403 page rather than a JSON response

[msikma]

This is a minor issue that I think only occurred because the IA is currently in process of getting the site back up.

When running ia metadata 'win95-logo.sys' (link: https://archive.org/details/win95-logo.sys), the following unhandled exception occurs:

Traceback (most recent call last):
  File "/usr/local/lib/python3.11/site-packages/requests/models.py", line 975, in json

    raise JSONDecodeError("Expecting value", s, err.value) from None
json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

During handling of the above exception, another exception occurred:

Logging the response reveals that the site sends an HTML response: https://gist.github.com/msikma/faa97e6509ec88754c325a66eb935650

The page itself states:

Item not available The item is not available due to issues with the item's content.

This is probably a rare case that will vanish when things are back online properly, but it might be nice to handle the case.

Thanks @msikma. Yes, this would be nice to handle.
