Rename new modelica models to clarify MBL version

[vtnate]

Any background context you want to provide?

We had to make some new models to support MBLv10. They were just named ..._new which could get confusing once we forgot when/why these were created.

What does this PR accomplish?

• Renames 2 models to clarify that they work with/are intended for MBLv10
• Update Docker readme to reference current version of our Dockerfile
  • This is not substantive. I happened to notice it when rebuilding the image locally

@nllong What naming convention should we use?

How should this be manually tested?

CI is sufficient

What are the relevant tickets?
