Invalid key signature for mysql-docker/8/debian11/8.0

According to the MySQL's Signature Checking Using GnuPG doc, the existing key has been expired.

The 3A79BD29 key expires on 2023-12-14. A new replacement key (A8D3785C) will sign upcoming MySQL 8.0.36 and higher packages. Both keys are installed by the MySQL repository setup packages released with MySQL 8.0.35, and both keys are also available at https://repo.mysql.com/.

The following GPG key does not match the one in the 'http://repo.mysql.com/apt/debian bullseye InRelease'.
