fix: switch to ghcr.io for eic images; rm older jug_* images

[wdconinc]

To avoid rate limiting on docker hub, switch to ghcr.io. Ref: https://support.opensciencegrid.org/support/tickets/public/971a44287b1ba434c46e7207e853cc18dc1be94e7f0a7ebc05a07216f23f11e9

Despite the test claiming it passed, it looks like using wildcards isn't supported for the GitHub container repo

Failed to get tags for image: ghcr.io/eic/eic_xl

(I suspect the sync code would have to switch to scrolling through e.g. https://github.com/eic/containers/pkgs/container/eic_xl/versions?filters%5Bversion_type%5D=tagged for ghcr.io URLs, seems... unpleasant)

Do you want to revert this, or should we avoid the globs for now and add line by line whenever a new release? We can do that for a month while we adapt dockerhub.py to support get_tags on ghcr.io.
