Fix in GCP configuration examples

[javiersanchz]

Description

A correction was made to the GCP configuration example. Blank spaces were removed, and the <project_id> and <subscription_name> fields within the section were deleted as they are specific to pubsub, as mentioned in issue number #6482 . Additionally, the remaining fields were added.

There is also a wrong example in the Configuration example section of the Local configuration (ossec.conf) > gcp-bucket page.

Please, update it too.
