Plan for versioning the "models" repo and plan for release

[puja-trivedi]

For models:

• create a dev_release_* branch that contains all the changes for a future release (so no more separate pushes to main branch)
  • perhaps it could be just dev and this branch name should be added to the GA workflows in places where we have main
• when a release is created all models irrespective of if changes were made to the model will get upgraded to the newest version
• adding version value to all the yaml files
• create GA that updates the version with each release
