`UnicodeDecodeError` with vcrpy 6.0.2 when using httpx

[ramnes]

Hey there, thanks for the great project!

I'm the maintainer of notion-sdk-py and when I update vcrpy to 6.0.2 for our tests, I can't use the cassettes it creates anymore. I can still successfully create the cassettes through pytest-vcr, but using them gives UnicodeDecodeErrors.

I first thought it would be an issue with pytest-vcr (especially as it's unmaintained), but replacing it with pytest-recording doesn't help, hence this issue. If it's an issue with both pytest-vcr and pytest-recording, just tell me and I'll open the issues accordingly. :)

Here is a PR that showcases the diff and the resulting CI errors:

• PR: Update to vcrpy-6.0.2 ramnes/notion-sdk-py#250
• CI: https://github.com/ramnes/notion-sdk-py/actions/runs/12550306943/job/34992856916?pr=250

        ``object_hook`` is an optional function that will be called with the
        result of any object literal decode (a ``dict``). The return value of
        ``object_hook`` will be used instead of the ``dict``. This feature
        can be used to implement custom decoders (e.g. JSON-RPC class hinting).
    
        ``object_pairs_hook`` is an optional function that will be called with the
        result of any object literal decoded with an ordered list of pairs.  The
        return value of ``object_pairs_hook`` will be used instead of the ``dict``.
        This feature can be used to implement custom decoders.  If ``object_hook``
        is also defined, the ``object_pairs_hook`` takes priority.
    
        ``parse_float``, if specified, will be called with the string
        of every JSON float to be decoded. By default this is equivalent to
        float(num_str). This can be used to use another datatype or parser
        for JSON floats (e.g. decimal.Decimal).
    
        ``parse_int``, if specified, will be called with the string
        of every JSON int to be decoded. By default this is equivalent to
        int(num_str). This can be used to use another datatype or parser
        for JSON integers (e.g. float).
    
        ``parse_constant``, if specified, will be called with one of the
        following strings: -Infinity, Infinity, NaN.
        This can be used to raise an exception if invalid JSON numbers
        are encountered.
    
        To use a custom ``JSONDecoder`` subclass, specify it with the ``cls``
        kwarg; otherwise ``JSONDecoder`` is used.
