Add opencontainer labels to Docker images

It would be great if the Docker container images had opencontainers labels. I have seen this across multiple other containers and believe this is the standard for labeling images.

https://github.com/opencontainers/image-spec/blob/main/annotations.md

Adding labels such as org.opencontainers.image.version will provide a way to obtain the current version of the running docker image which can be useful in automating the process of checking for updates.

Doing a docker inspect on the current images shows no labels. Here is an example of the Jellyfin docker image with opencontainers labels:

"Labels": {
    "org.opencontainers.image.description": "The Free Software Media System",
    "org.opencontainers.image.documentation": "https://jellyfin.org/docs/",
    "org.opencontainers.image.source": "https://github.com/jellyfin/jellyfin",
    "org.opencontainers.image.title": "Jellyfin",
    "org.opencontainers.image.url": "https://jellyfin.org",
    "org.opencontainers.image.version": "10.9.8"
}

Start by reviewing the repository's Docker image build configuration and compare the available image metadata with the OCI annotations specification linked in the issue. Add appropriate opencontainers labels, including a version label that reflects the image version, and verify with docker inspect that the built images expose the labels.
