Make token for access to GHCR:

A. Generate the Fine-Grained PAT (only works if you select the repo with the container registry)

1. Go to https://github.com/settings/personal-access-tokens → Fine-grained tokens

2. Repository access: Select the specific repository where the image lives. Permissions: Packages → ✅ Read access Contents → ✅ (optional if cloning is needed) 🔐 This token can now access GHCR images built from that one repo.

B. Use a classic token, with packages:read and repo
