### Name of the resource

AWS::InspectorV2::Filter

### Resource name

_No response_

### Description

**New attribute for an existing resource is desired**

On the [PackageFilter](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-inspectorv2-filter-packagefilter.html) type (used in [FilterCriteria.VulnerablePackages](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-inspectorv2-filter-filtercriteria.html#cfn-inspectorv2-filter-filtercriteria-vulnerablepackages) of the [AWS::InspectorV2::Filter](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-inspectorv2-filter.html) resource), add support for the `FilePath` attribute.

This attribute is already available on the [API](https://docs.aws.amazon.com/inspector/v2/APIReference/API_PackageFilter.html#inspector2-Type-PackageFilter-filePath) (used in [CreateFilter](https://docs.aws.amazon.com/inspector/v2/APIReference/API_CreateFilter.html)), but is missing on CFN.

### Other Details

_No response_

Start with the PackageFilter documentation and the FilterCriteria.VulnerablePackages section, then compare them with the CreateFilter API's PackageFilter definition. Done means AWS::InspectorV2::Filter accepts and documents FilePath within VulnerablePackages consistently with the API.
