chore(mysql): change mysql auth mode to new default (caching_sha2_password)

[marcelgerber]

The MySQL 9 client, which came out last week, removes the deprecated mysql_native_password auth mode.

This means that you can't log into the server if the server uses that mode as its auth mode, which for us was the case.
Or, more specifically, the Waiting for MySQL to come up... check will never succeed.

This PR makes it so we are using the default auth mode (caching_sha2_password).

Notes

The actual change will only take place once the database is rebuilt, or you manually run an ALTER USER command.
I tested it out, and existing databases will remain in full working order even if these command line args are not present - they'll just continue using mysql_native_password as the auth mode.

Recreate DB

To re-create a DB from scratch, it's easiest to run docker volume rm owid-grapher_mysql_data_public and then make up to have it recreated.
This will delete all tables and databases that exist in this mysql instance. If that's not an option, there are also other options available.
