Adds a DockerPackageUpdater that rewrites vulnerable base images in Dockerfiles.
Given a fix version from Xray, it locates each Dockerfile from the scan evidence, finds the matching FROM <image>:<version> line, and rewrites the tag or digest in place — preserving registry prefixes, AS <alias> stage names, --platform flags, and case-insensitive FROM keywords.
