The test creates 10000 modules, which runs in less then one second in
release builds, but can take much longer with stress flags and on
special bots.
It timed out on the tsan isolates bot in a variant passing
--stress-wasm-code-gc.
Since the test should only verify that we support more than 1000
modules in a single isolate, we do not need to run it in that variant.
Thus just skip it.
