Support VCR.py >=5 (fixes #111)

[hartwork]

Description

Partial pull request for support for VCR.py >=5 as offered at https://github.com/kiwicom/pytest-recording/issues/111#issuecomment-1651595271 . I lack the bandwidth to re-write the two tests marked as "todo" at the moment, but I should find time for smaller adjustments/additions that come up during review. Thanks for your understanding.

Checklist

• [ ] Created tests which fail without the change (if possible)
