Thank you for the PR, however, according to our contribution guidelines:

We are likely to consider suggestions to curate a topic or collection that is valuable to GitHub's community. Valuable topics, for example, include those that are already widely used by repositories and could benefit from the addition of important information. When suggesting content, please consider how to make your contribution broadly useful and relevant to others, rather than serving a specific use case.

This topic is only used on 28 repositories, therefore it does not qualify as "widely used".
