The create subscription section is not needed, the subscription is automatically created when the topic is created.

Description

The documentation of pub sub GCP module for Wazuh lacks of examples inside the documentation.
You have to look at the user manual section when the bucket configuration has an example inside its own section.
Also, the credentials folder specified in the config example doesn't match with the 4.3.0 directories
Example: wodles/gcp-pubsub
Real folder: /var/ossec/wodles/gcloud/pubsub/

I wish to include a better explanation of what is each parameter. The current documentation seems to lack of detail to fully understand what parameters are required into Wazuh configuration block.
Being direct the project id tag need to be the project ID related to the topic created in our case wazuh-dev-258815
and the subscription name is the name given to the subscription at creation time in our case wazuh-gcloud-test-sub2

GCP bucket config example

<gcp-bucket>
   <run_on_start>yes</run_on_start>
   <interval>1m</interval>
   <logging>debug</logging>
   <bucket type="access_logs">
       <name>wazuh-gcloud-test-bucket</name>
       <credentials_file>wodles/gcloud/pubsub/credentials.json</credentials_file>
   </bucket>
 </gcp-bucket>

Required permissions.
