fix(dump): pass --column-statistics=0 for MySQL 8 mysqldump on MariaDB, release as 0.0.7

Backport for the Shopware 6.6 line. When the server is MariaDB but only
MySQL 8's mysqldump is installed (e.g. dockware/web), the dump aborted
with "Unknown table 'COLUMN_STATISTICS' in information_schema (1109)".
