fix: repoint ArgoCD Applications from GitHub to in-cluster Forgejo

homelab-root and every child Application still tracked github.com/Riotpiaole/riotpiao.homelab.com, which had diverged from origin (Forgejo) for a while - pushes to Forgejo were never picked up by ArgoCD. Repointed to forgejo.riotpiao.com/rock/homelab.git, already covered by the AppProject's rock/* wildcard.
