Add warning to last step

[Tostti]

Description

This PR adds a message to warn the users that a step documented in some SSO documentations should not be done in versions equal or higher than 4.3.10.

This is because that step was a workaround for an issue that will be resolved on 4.3.10 on PR wazuh/wazuh-dashboard-plugins#4815

If the users make this change on 4.3.10 or higher, the logout will not work anymore on any site of the application, for that reason is important to mark that it should not be done and not that is not necessary.
