CZ: Remind to check and replace API keys in code

Odaily reported that CZ posted on platform X, stating that if there are API keys in the code, even in private repositories, it is now time to re-check and replace them.

GitHub is currently investigating unauthorized access to internal repositories. Although there is currently no evidence of an impact on customer information stored outside of GitHub's internal repositories, such as customers' enterprises, organizations, and repositories, subsequent infrastructure activity is being closely monitored.
