Config: Make PhotoPrism compatible with MariaDB 11

[lastzero]

While testing the upcoming MariaDB release, we noticed that it is no longer fully compatible with mysql - at least as far as commands are concerned.

As a result, we will now use:

• mariadb instead of mysql for the client binary
• mariadb-dump instead of mysqldump for the backup binary
• and mariadbd instead of mysqld for the server binary

If you know of any other changes that should be implemented or have found an incompatibility, please let us know so we can update our application and/or Docker image. Thank you!

Our config examples at https://dl.photoprism.app/docker/ have been updated. To update your existing docker-compose.yml file, replace command: mysqld with command: mariadbd, otherwise the database server might fail to start.

The MariaDB Troubleshooting Guide in our documentation has been updated accordingly:
