[tags/v0.4.0-rc1] In Dockerfile, does not use yarn command

[hyenjong-yoo]

Using Faucet Dockerfile

but not in package.json script command.

[hyenjong-yoo]

insert into this line

"pack-node": "yarn build-or-skip && webpack --mode production --config webpack.node.config.js"

at faucet/package.json works well.
