Warning notice used incorrectly

[karyware]

Example page: https://docs.emqx.io/en/broker/v4.3/rule/rule-example.html

The word "Warning" is used incorrectly throughout the documentation. It should only be used when the user's actions could cause something bad to happen, such as deleting a cloud deployment. Maybe "NOTE", or just an information icon would be better in most cases.

Warning could be appropriate here: https://docs.emqx.io/en/cloud/latest/deployments/delete_deployment.html
