ghcr.io releases are disappearing

[RichieSams]

Hi! Thanks for continuing mtail on.

A few months ago, I switched my usage from the old google mtail docker container to your ghcr.io repo. And everything was working well. Today, I was doing work on my repo, and I got a test failure, because it's failing to find the docker image in ghcr.io

ghcr.io/jaqx0r/mtail:3.0.16

Does ghcr.io have some kind of limit to the number / frequency of tags? If I look at your repo, there are only 14 tags: https://github.com/jaqx0r/mtail/pkgs/container/mtail/versions?filters%5Bversion_type%5D=tagged

Also, it looks like you're pushing a new tag every week on a cron job: https://github.com/jaqx0r/mtail/blob/main/.github/workflows/tag-new-release.yml

Can you explain why? If the code hasn't changed, why do we need a new tagged release?

Thanks!
