Filebeat audit resource name visualization uses an invalid field

[pmusa]

Version: 7.12.0 (it was also in 7.10.1, did not test any other versions)

Steps to Reproduce

• install and setup filebeat
• navigate to Dashboard -> [Filebeat GCP] Audit
• One of the visualizations will show an error:

Could not locate that index-pattern-field (id: gcp.audit.resource_name)

Steps to quickly fix it

• Inspect the visualization saved object (Audit Resource Name [Filebeat GCP])
• Update the visState to use googlecloud.audit.resource_name instead of gcp.audit.resource_name

I think the issue is related to the rename that happened here
