doc: move OCI images hosting to ghcr.io

- dockerhub free team accounts will be deleted in < 30 days (https://www.docker.com/blog/we-apologize-we-did-a-terrible-job-announcing-the-end-of-docker-free-teams/), this affects the Shaarli team account
- automated builds will keep pushing latest builds to dockerhub in addition to gchr.io, until the account is deleted
- **users relying on `shaarli/shaarli` OCI images are advised to migrate to `ghcr.io/shaarli/shaarli` as soon as possible**
- existing tagged images have been copied from https://hub.docker.com/r/shaarli/shaarli/ to https://github.com/shaarli/Shaarli/pkgs/container/shaarli/versions?filters%5Bversion_type%5D=tagged
- prepend `ghcr.io/` to all references to OCI images
- update all references to dockerhub -> github packages registry, update developer documentation, cleanup dead links
- ref. https://github.com/shaarli/Shaarli/issues/1948
