The python binaries on some CI images and dev boxes ship stripped, so the allocator frames in an interpreter-shutdown leak come through unsymbolised (/usr/bin/python3.13+0x...) and the function-name matches above cannot apply. leak:python3.10 already handled this for 3.10, and a stale comment claimed 3.12 does not leak. Add leak:python3.12 and leak:python3.13, mirroring the 3.10 entry, so the interpreter globals are suppressed whatever CPython the build uses. Signed-off-by: Kefu Chai <k.chai@proxmox.com>
