Subject: [PATCH] build: suppress -Wfree-nonheap-object false positives in
 lua_cjson #37250

Problem:
Building with GCC emits -Wfree-nonheap-object warnings in lua_cjson code
when calling strbuf_free(), despite the free being conditionally valid.
This is an unresolved GCC issue: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=98753

Solution:
Supress warnings with the -Wno-free-nonheap-object flag for now.
