[FAB-17262] Fix instructions in build_network
[FAB-17262] Fix instructions in build_network

This patch fixes instructions described in
`docs/source/build_network.rst` as follows:

* Add `docker-compose-etcdraft2.yaml` to the commands to start network
with docker-compose, because other operations assume to use
`SampleMultiNodeEtcdRaft` profile

* Change the directory name from 'node' to 'javascript' for the command
that packages Node.js chaincode according to the current source code in
`fabric-samples`

* Add vendering operations before packaging Go chaincode

Also, this patch includes the other minor fixes.
