Update logo for compatibility with Project Browser

Problem/Motivation

A logo has been created by the community for your module for compatibility with Project Browser. Please consider adding this logo. The logo will be displayed in the card for your module in the Project Browser (as well as on drupalcode.org as your project avatar, and on drupal.org on your project page).

Proposed resolution

The logo to be used should be this exact image (we have already ensured it meets requirements for size, etc.)

Remaining tasks

INSTRUCTIONS: The logo should be added to the root folder of the repo, and be named logo.png. This must be present on your project’s default branch. This logo will be displayed on the cards in the Project Browser grid and list views (and on the Drupal.org project page next to the page title). If you have previously added a logo as the first image in the Images field on your project page, please remove it. Project Browser will no longer be using the first image as the logo.

Once this issue is marked as "Fixed", the Project Browser maintainers will close the Related issue in the Project Browser project and give folks credit
