fix: remote xlsx file reading with python 3.12 (#1684)

- fixes #1642 

Adapt to changes of API of `_TemporaryFileWrapper` in python 3.12,
unfortunately not intercepted by pyright (see issue for details). The
fix does not rely on this class's API, as the value is already stored in
a local variable.
