Build/Test Tools: Support older MariaDB versions in local Docker envi…

…ronment.

Older versions of MariaDB did not contain the `mariadb-admin` command. This command is configured as the `healthcheck` used by the local Docker environment to confirm that the database container has successfully started and is reporting as “healthy”. The current result is a failure when starting the environment while using one of the affected older versions.

For MariaDB versions 10.3 and earlier, the `mysqladmin` command was used instead. Since WordPress still technically supports back to MariaDB 5.5, the local environment should support running these versions. This updates the environment configuration to take this into account when performing a `healthcheck` test.

The README file is also updated to reflect that the same workaround added in [57568] for MySQL <= 5.7 is required when using MariaDB 5.5 on an Apple silicon machine.
