Get RequestV2Definition by ID

A reusable template that defines the structure and configuration for requests in Benchling. Also known as a "Request Template" in the UI. Each RequestV2Definition specifies a templateDocument that serves as the document template for requests, a workflowTaskSchema that defines the task structure and fields, and a prefix used to generate human-readable display IDs (e.g., "REQ-001") for submissions created from this template. Request templates are organized within TemplateCollection folders and support collaboration features like starring (see Starrable). When users submit a request, they create a RequestV2Submission based on this definition. The template can include a description to explain its intended use and can be archived when no longer needed.
