Pin predictions to a specific model version

The predictions endpoint now supports running against a specific version of a model. Pass the version number after the model name using owner/name:version_number. Without it, predictions run against the latest version as before.

This is useful when a model you depend on releases a new version that changes behavior. Pinning to a version means your app keeps running against the same model until you decide to upgrade.
