Push command fails when using `Say` node in workflow

[adiixs]

Description

Push command fails if we use Say node in workflow.

Reproduction steps

elevenlabs agents init
elevenlabs agents pull --agent <agent-id>
elevenlabs agents push

Note: the workflow must have a Say node.

Actual behavior

The push command fails with the following error:

Error processing <agent-id>: Error: workflow -> nodes -> node_X -> type: Expected enum. Received "say".; workflow -> nodes -> node_Y -> type: Expected enum. Received "say".; workflow -> nodes -> node_Z -> type: Expected enum. Received "say".

Expected behavior

The agent push command should be executed successfully since it is configurable from the UI.
