【建议】纠正standalone模式中的部署文档中一处错误

[william-peng-cn]

https://github.com/apache/dolphinscheduler/blob/3.1.4-release/docs/docs/zh/guide/howto/datasource-setting.md

将mysql-connector-java驱动加到./standalone-server/libs/standalone-server/目录下,

应当更正为

将mysql-connector-java驱动加到./tools/libs/目录下,

我安装文档步骤修改了元数据库，但是启动的时候仍然在找 org.h2.Driver 驱动，是否还有其他位置需要修改？

我是启动的standalone-server，参考官方文档报错信息跟你类似，修改了apache-dolphinscheduler-3.1.5-bin/standalone-server/conf中的application.yaml配置文件里面datasource，重新启动成功。
