chore(cloudflare-tunnel-gateway-controller): deploy the v5.0.0 candidate

Run the PR #989 build (201257db: master plus the v4 to v5 upgrade
guide) from ttl.sh, with both images pinned by digest, to verify v5.0.0
on the production tunnel before tagging. Revert to the ghcr.io release
chart once v5.0.0 is published.
