Preventing and detecting ransomware with Wazuh". Its content	#12875 (Test 7)

After reviewing the post and testing the use case with Wazuh 4.3, the content is updated but the Alerting module screenshots got outdated. We should replace them with the new captures. Feel free to use the screenshots at the source issue, if suitable.

Adding to the original comment, during the second iteration of the manual testing of the blogpost for v4.3.0, I detected that the post uses OpenDistro references instead of WazuhDashboard in the Alerting module section.
