MySQL connection wait_timeout too small? (unsure of good title)

Description

Describe the bug

When BentoBox is connected to a database, it causes some errors to show in console after long periods of no activity. The example I have shows that it last received a packet 60,522,509 ms ago.

[03:58:47 ERROR]: [BentoBox] Could not check if key exists in database! db8e5b84-c670-41f6-9a2b-1ad9a8c7e104 The last packet successfully received from the server was 60,522,509 milliseconds ago. The last packet sent successfully to the server was 60,522,510 milliseconds ago. is longer than the server configured value of 'wait_timeout'. You should consider either expiring and/or testing connection validity before use in your application, increasing the server configured values for client timeouts, or using the Connector/J connection property 'autoReconnect=true' to avoid this problem.

Steps to reproduce the behavior

1. Connect BentoBox to a database.
2. Start the server, make sure the connection is valid.
3. Wait for a while.
4. Join the server.
5. Observe the error in console.

Expected behavior

There should be no error.

Take backups, of course, but here are the steps:

1. Stop server
2. Take a backup of the world folders, BentoBox folder, and database. 😃
3. Edit the BentoBox config.yml file to use the database MARIADB2JSON. Keep your MariaDB instance running.
4. Start the server.
5. Once BentoBox fully boots up, run /bbox migrate.
6. Once it’s all copied over, stop the server.
7. Change the database to JSON.
8. Restart.

That should do it.

That worked perfectly. Thank you for the support!
