Fixing nodes in ms2.launch.py

Closes #590 (closed)

Notes for Reviewers

I recommend changing registry.gitlab.com/autowarefoundation/autoware.auto/autowareauto:master to registry.gitlab.com/autowarefoundation/autoware.auto/autowareauto:590-fix-ms2-launch and testing from /opt/AutowareAuto instead of building from source. This allows the use of the map YAML configuration file without modification.
