Where can I see when a GitHub repository was made public?

Let's consider, for example, the GitHub repository, https://github.com/langchain-ai/auto-evaluator. Where can I see when a GitHub repository was made public?

Notes:

1. I don't have any special access to the GitHub repository. E.g., I'm not the owner, and I'm not a collaborator.
2. The question isn't related to developing a program.
3. I Googled the question but I couldn't find the answer.
