// Some MariaDB version strings prepend a fake MySQL version to the front,
// which is always "5.5.5-". This was done to so that old MySQL clients
// could connect to newer MariaDB servers.
// For example, 5.5.5-10.5.11-MariaDB:
// - 5.5.5 is a fake MySQL version.
// - 10.5.11 would be the actual MariaDB version.
// See https://github.com/MariaDB/server/blob/f6633bf058802ad7da8196d01fd19d75c53f7274/include/mysql_com.h#L42
// Remove any leading MySQL 5.5.5- prefixes:
