Timeout prevents Node.JS from exiting

[drcrallen]

Environment details

• Programming language: Javascript
• OS: Windows
• Language runtime version: Node v20.3.1
• Package version: 1.1.0

Steps to reproduce

1. Construct a vertexAI.getGenerativeModel with a timeout specified in the requestOptions
2. Finish the node script.

3. nodejs-vertexai/src/functions/post_request.ts

   Line 97 in 2ec9e7d

   setTimeout(() => abortController.abort(), requestOptions.timeout);

   prevents node from exiting until the timeout elapses

Expected behavior: I would like the ability to set a timeout but also exit node immediately without waiting for the timeout to elapse.
