Sure, you're providing some code for free. Obviously you don't owe anyone anything. But conversely, nobody owes you their time or attention just because you wrote something.
If you want people to actually use your code, you probably need to take some responsibility. And listen to the criticisms others have shared here.
Instead of "latest" or no version tag, I think you'd just need to put the desired version in your compose file.
In this case it sounds like you want to upgrade to 10.10.7 first, so you'd use that for your tag. Based on the tag I found here: https://hub.docker.com/layers/jellyfin/jellyfin/10.10.7/images/sha256-3b38dae4c3ddd6ebc7378538fba4d3f314070ebefbdb3d688166b7c8658fb123
After updating your compose stack to that version and confirming a successful upgrade in jellyfin, then you could remove the version tag (to pull latest by default).
