Remove logger.warning introduced in emscripten-core#20562

Using `logger.warning` here instead of `diagnostics.warning` means that
this warning cannot be suppressed and I'm now seeing this for all
wasm64 tests.

Probably better to simply not show a warning here since we don't
show warnings when `feature_matrix.caniuse` disables other features.
