Change a voice agent

PATCHhttps://api.norreach.app/v1/voice-agents/{id}

Changes an agent's name, description, language, first message, script, voice or number, as the app's agent editor saves it. A published agent's new script is used from its next call (as the app's edited scripts are); its voice and tools change when it is published again in the app. Owners, admins and managers. dry_run=true answers it as it would be.
