Subject: [PATCH] Docker: Back to npm from yarn (#4730)

This commit reverts "Fix Dockerfile #4214" which uses yarn instead of npm.
The cause of the build error is that binding.gyp and src/crypto_key.cc
are missing when installing dependencies.
In other words, yarn did not fix build error.

There is no reason to use yarn, so go back to npm.
