Update to v3.1 of the Computer Vision Analyze API

Description of the Change

We are currently using the v1.0 Computer Vision Analyze API, while the most recent is v3.1. This PR updates the API endpoint to v3.1.

Testing this locally, I did not run into any issues or regressions with this update. In addition, I've looked through the documentation for each version of the API:

• v1.0
• v2.1
• v3.0
• v3.1

When it comes to the analyze endpoint, no features have been removed and the response(s) provided are the exact same.

The differences are with newly added features:

• Brands: detects various brands within an image, including the approximate location
• Objects: detects various objects within an image, including the approximate location

And newly supported languages:

• Spanish
• Japanese
• Portuguese

Alternate Designs
