dingding_message_type: The error was: TypeError: unhashable type: 'list'

[devbean]

SUMMARY

Use dingding_message_type of grafana_notification_channel in storybook will cause error: The error was: TypeError: unhashable type: 'list'.

After reading the code I found that might because of this code line. (PS: I'm not familiar with Python though)

Since dingding_message_type should be string only so I think it is OK to change dingding_message_type type to string.
