fix: switch container registry from GCP to GHCR

- Replace Parity's GCP registry (europe-docker.pkg.dev/parity-ci-2024)
  with GitHub Container Registry (ghcr.io/pezkuwichain)
- Add packages:write permission for GHCR push
- Update zombienet-env to use pezkuwichain images
- Fix paritypr references in zombienet tests
