fix: correct Windows checksum for wasm-tools v1.241.2

The Windows checksum was incorrect, causing CI failure. Updated to the
correct SHA256: 9eb1af8331ec073d37bb025598426dcb747bd51db085861066e123b9e823fa52

This was discovered from the CI error message which showed the actual
checksum that was downloaded.
