fix: allow matrix-sdk-crypto-nodejs build scripts for native binary

pnpm 10 blocks build scripts by default. The matrix-bot-sdk requires
@matrix-org/matrix-sdk-crypto-nodejs which downloads a platform-specific
native binary via postinstall. Added to onlyBuiltDependencies so the
Alpine (musl) binary gets installed in Docker builds.
