feat(resource metadata): add resource metadata to JSON OCSF

[MrCloudSec]

Context

This PR renames the resource_metadata field to resource across the codebase for consistency and clarity. Additionally, it includes the necessary changes to enable and finalize the integration of resource metadata for all supported providers (AWS, GCP, Azure, and Kubernetes) in the OCSF JSON output. This ensures detailed and structured resource information is captured and exported in the findings.

Description

• Renaming resource_metadata:
  • Replaced all instances of resource_metadata with resource to improve readability and consistency.
  • Updated constructors and calls to reflect this change across the relevant files.
• Finalizing Resource Metadata Inclusion:
  • Enabled the inclusion of detailed resource metadata for AWS, GCP, Azure, and Kubernetes in the OCSF JSON output.
  • Ensured the data field now contains both details and metadata for each resource:

"data": {
    "details": "resource-specific details",
    "metadata": {
        "id": "resource-id",
        "name": "resource-name",
        "region": "resource-region",
        "tags": [{"key": "tag-key", "value": "tag-value"}]
    }
}
