fix log_warning call with missing arguments

Fixed TypeError in warnings.py where log_warning was called with only 2
arguments instead of the required 4 positional arguments (logger,
message, subtype, location). This was causing crashes when processing
invalid warning filters in Sphinx 8.x.

The fix ensures compatibility with the updated log_warning function
signature introduced for Sphinx 8.x compatibility.
