Fix(prediction): add missing "aborted" status to Prediction model

The Replicate API sometimes returns a "status": "aborted" value for predictions
that were interrupted before completion. The current pydantic model does not
include this status, which causes a ValidationError:

    pydantic.v1.error_wrappers.ValidationError:
    unexpected value; permitted: 'starting', 'processing', 'succeeded', 'failed', 'canceled'

This commit updates the `Prediction.status` Literal to include "aborted"
to match the current API behavior.
