Use the mariadb executable for SQL commands where possible

On newer versions of MariaDB e.g. 11.4.3, the following warning is shown:

mysql: Deprecated program name. It will be removed in a future release, use '/usr/bin/mariadb' instead

Thanks. Can we not count on mariadb existing? Mysql and postgres count on their program existing.

I did think that, but did it this way to maintain as much backwards compatibility as possible just like the dump command does.

Based off the MariaDB documentation:

Prior to MariaDB 10.5, the client used to be called mysql, and can still be accessed under this name, via a symlink in Linux, or an alternate binary in Windows.

Drupal 10 currently requires MariaDB 10.3.7+ and can confirm from a quick test in docker lab, the mariadb binary only started being included around 10.4 despite what the doc says:

~$ docker run -it --rm mariadb:10.3.7 /bin/sh -c 'which mariadb'
~$ docker run -it --rm mariadb:10.4 /bin/sh -c 'which mariadb'
/usr/bin/mariadb

So the executable check will need to be removed once support for MariaDB <10.5 is dropped.
