Due to changes in node v17+ to work with OpenSSL v3.0, MD4/MD5 hash
algorithms no longer can be used out-of-the-box with Webpack
(https://github.com/webpack/webpack/issues/14532).

We can't switch to another hash algorithm like SHA256 until we upgrade
to Webpack v5 (https://gitlab.com/gitlab-org/gitlab/-/issues/350120),
but we can make the latest node version work by specifying
`--openssl-legacy-provider` in `NODE_OPTIONS`.

We use a separate build script (`webpack-prod-node-latest`) because
older versions of node will fail if `--openssl-legacy-provider` is used.
