Fix: [CI] Disable CodeQL TRAP Cache, as it trashes our cache (#13832)

Each cache is ~1GB. And you can only have 10GB of cache. So after
10 runs, our cache is full of trap caches.

The kicker? We don't actually benefit from this cache. It is only
used if you re-run CodeQL over the exact same codebase (without
changes), to quickly re-evaluate the latest CodeQL set. We are
way to active to have any benefit from that, and we don't run
CodeQL on a schedule to ever pick up on the cache.
