// This example demonstrates how to manage topics in GitLab using the GitLab API client.
// It covers the following steps:
// 1. Initialize the GitLab client with a personal access token.
// 2. Create a new topic by specifying its name and description.
// 3. Set an avatar for the topic by uploading an image file.
// 4. Remove the avatar from the topic.
// 5. Log the details of the topic at each step to verify the changes.
