Add suppression for 1.93+ std::thread::new()

Apparently the `std::thread`-module was restructured, so that the
`std::thread::Thread`-type now resides in `std::thread::thread::Thread`
instead, thus the suppression needs to be updated as well. Instead of
changing the old one, a new one is added to stay compatible with 1.84.
