fix: cloudfoundry_app and cloudfoundry_apps datasource does not return instances attribute

[ANUGRAHG]

Purpose

• This PR fixes an issue where top-level process attributes in the cloudfoundry_app and cloudfoundry_apps data sources were always returned as null.
• The cloudfoundry_app and cloudfoundry_apps data sources expose top-level attributes from the web process (e.g. instances, memory, disk_quota, health_check_type, command, etc.) via datasourceProcessAppCommonSchema()
• Although these attributes were defined in the schema, they were never populated from the corresponding web process, causing them to always return null.
• Now, after populating each Process struct in the loop, the web process fields are copied to the matching top-level fields on DatasourceAppType.
• closes [BUG] Data Source for cloudfoundry app and cloudfoundry apps does not retun values in attribute instances #472
