Update Transformer

PUThttps://api.confident-ai.com/v2/transformers/{transformerId}

Renames a transformer, changes its description, or replaces its code, and returns it. Sending codeDefinition overwrites the stored code, which every AI connection and metric collection already using this transformer picks up on its next run.
