Include org.opencontainers.image.version labels in email notifications when a new image is found. Both the old (current) and new image versions are displayed on a single line, making version transitions easy to see at a glance. Example output: Found new image: ghcr.io/homarr-labs/homarr:latest (b7734c440450) v0.15.0 -> v0.16.0 The version is extracted from the new image during the staleness check and from the running container's labels for the old version. Images without the OCI version label are displayed without version info.

What This PR Does
It adds the opencontainers image version to the update log if it exists on the container to give a better description of what the upgrade actually is.
As the issue that I linked below points out,
org.opencontainers.image.versionis a piloted standard to bring more consistency to container labels. All containers built via GitHub actions add them. Additionally, all containers from linuxserver contain them as well.Related Issues
This is partially related to #1848
Although in that issue, they were asking that this information be added to watchtower's templating function. I don't actually use the templating function, so I didn't put it there, but I would imagine that making container labels available via the template functions would be a much larger PR.
Testing
I have been running with this setup for several days and it has worked great for me.
