// Node 17+ ships with OpenSSL 3 by default, so we may need the option
// --openssl-legacy-provider so that webpack@4 can use the legacy MD4 hash
// function. This option doesn't exist on Node <17 or when it is built
// against OpenSSL 1, so we have to detect Node's major version and check
// which version of OpenSSL it was built against before spawning the process.
//
// Can be removed once the webpack version is upgraded to >= 5.61,
// which no longer relies on Node's builtin crypto.hash function.
