fix: integer div by zero stdlib test cases

[batatovich]

Summary

The stdlib expected div by zero test cases to abort with a specific arithmetic error, but the wasm runtime aborts traps when this case is encountered. We simply commented this case on the stdlib, as even thou it fails, the behavior is reasonable and informative for the user.

Changes Made

• Commented div by zero cases in stdlib
