[BUG]Dynamically updating the default_time_zone parameter generates an error message, and it is not allowed to modify the default value. Is there any way to change this

[xpy3306]

1、kbcli cluster configure test-mysql --set=default_time_zone='+8:00' -nmysql
error: parameter[[default_time_zone]] is immutable, cannot be modified!

2、kbcli cluster edit-config test-mysql --config-spec=mysql-consensusset-config -nmysql
error: parameter[[default_time_zone]] is immutable, cannot be modified!

The above methods all report that modification is not allowed

default_time_zone is marked as immutabled, that's why it cnanot be udpated.

@sophon-zt @xuriwuyun pls help check the parameters of MySQL. It seems some parameters listed in immutableParameters should be removed.
