Get Images From Files Action

A reusable Gitea Action, that extracts docker images from selected files in a repository.

The action supports Dockerfiles and Kubernetes manifests. Other files are supported if they have a recognizable image reference. Duplicate image references are deduplicated.

Note: Only fully-qualified refs (with registry, e.g. docker.io/library/alpine:latest, gcr.io/distroless/static:nonroot@sha256:...) are included; short refs like alpine:latest are omitted as their use is discouraged.
