fix(ci): remove duplicate runner Deployment from apps/

The stale apps/gitea-runner.yaml contained two Deployment manifests
that conflicted with the canonical Deployments owned by the
gitea-runner-config Argo Application (pointing at k8s/gitea-runner/).

Dual ownership caused Argo CD to fight itself — restarting runner
pods mid-job and producing the "context canceled" failures on
neuron-technologies/dharma-el CI.

Canonical Deployments (config-version 2026-05-04-cf-access-public-url,
docker.sock, CF Access env, replicas=2 for nt-runner) live in
k8s/gitea-runner/deployment.yaml and are managed by gitea-runner-config.
