feat: add imageManifest column to the aws_ecr_repository_images table

[arruw]

Which problem is this feature request solving?

I would like to find dependencies between different OCI images by analysing image manifest data. Usually you can tell if a two images are related (paren/child) if first one or more layer digests are matching.

Example: Image X contain security flaw. Find all images that were build from image X.

Describe the solution you'd like

Add a new column called imageManifest to the aws_ecr_repository_images table.

imageManifest can be fetched from this API: https://docs.aws.amazon.com/AmazonECR/latest/APIReference/API_BatchGetImage.html
