Docker Hub image out of date

[schnaser]

Latest release is as of this writing 2.8.0, but docker hub image at https://hub.docker.com/r/mxpv/podsync is 2.5

Use ghcr.io/mxpv/podsync as stated in the README

[v2px]

doesn't change the fact that it's out of date. if it's not going to be updated anymore maybe it should be taken down so people don't install outdated and potentially unsafe images.

The suggestion is valid. I've removed the image from Dockerhub. Images are published on ghcr.io.
