Fix(connector): gracefully handle LANG environment setup failures-Update ssh.go (#2552)

* Update ssh.go

setenv 会导致在kk 3.1.8/3.1.9 在centos/rockey linux 9.x下ssh fail ，无法部署； 经过验证，不设置语言对在centos/rockey linux 9.x部署没有影响，建议setenv改为尽力而为方式更合适，，设置失败产生Warn即可。

* Update ssh.go

修改Setenv告警日志显示 Localization warning  为Warning ，更符合一般习惯

* Fix:  no sudo env  export fail

Check chown operator

* Update ssh.go

部署测试模拟发现，如果设置失败会大量产生这种Warning，可能因为部署过程kk有大量ssh连接操作的缘故，故降到Debug级别
