Update dashboard settings screenshots

Description

Closes Issue #6677
Updated dashboard settings screenshots. The screenshot that triggers the issue is the API tab screenshot because we added the Version and Updates State columns, the Check Updates button, and the Disable update notifications option. The other screenshots have also been updated to be consistent with the Wazuh UI, such as the top bar.
