[3.13] gh-119369: Fix deadlock during thread exit in free-threaded build (GH-119528) (#119868)
Release the GIL before calling `_Py_qsbr_unregister`.
The deadlock could occur when the GIL was enabled at runtime. The
`_Py_qsbr_unregister` call might block while holding the GIL because the
thread state was not active, but the GIL was still held.
(cherry picked from commit 078b8c8cf2bf68f7484cc4d2e3dd74b6fab55664)
