CZ: Reminder to check and replace API keys in code

Odaily, CZ posted on platform X, stating that if there are API keys in the code, even in private repositories, now is the 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 customer enterprises, organizations, and repositories, subsequent activities on the infrastructure are being closely monitored.
