test(plugins): drop duplicate SDK-alias loader case that timed out under load (#125134)

The deleted case took ~54s and exceeded the 120s per-test timeout under CPU contention. Its coverage is already provided by the sibling pre-split SDK bridge case, which spans both private-local-only and public alias classes, and by extensions/llama-cpp/index.test.ts.
