[BUG] GHCR: container build failed after migrating

[drwetter]

... from https://github.com/drwetter/ to https://github.com/testssl/

Looks like an auth issue.

GH action failed is here: https://github.com/testssl/testssl.sh/actions/runs/12635150187 .

Could need some help or a cookbook what do do here as I am not really competent as far as that is concerned.
