[bug\_fix] error:0308010C:digital envelope routines::unsupported

Set the environment variable \`NODE\_OPTIONS=--openssl-legacy-provider\` to enable the legacy OpenSSL provider, or upgrade webpack to v5.61.0\+ \(or the specific tool\) which replaced the incompatible MD4 hash algorithm.

Journey Context:
Developer upgrades to Node.js 17 or 18 \(which uses OpenSSL 3.0\) and tries to build an existing React or Vue project using webpack 4 or 5 < 5.61. The build immediately crashes with an OpenSSL error about "digital envelope routines::unsupported" or "error:0308010C". The developer searches and finds conflicting advice about downgrading Node.js. Instead, they learn that Node 17\+ introduced a flag to enable the legacy OpenSSL provider. On Linux/macOS, they prefix the build command: \`NODE\_OPTIONS=--openssl-legacy-provider npm run build\`. On Windows PowerShell, they use \`$env:NODE\_OPTIONS="--openssl-legacy-provider"\`. The build succeeds. Later, they upgrade webpack to v5.61.0\+ which replaces the crypto.createHash\('md4'\) call with a wasm implementation, removing the need for the flag.
