ci: drop cache: setting in setup-go/setup-node

`cache: true` (setup-go) and `cache: pnpm` (setup-node) make the
actions push and pull tarballs through the Gitea Actions cache
service at 192.168.0.222:43513. That endpoint currently does not
answer, so every workflow burns minutes per run on reserveCache
retries before the action gives up.

In host-mode the real caches live under the runner user's $HOME
(~/go/pkg/mod, ~/.cache/go-build, ~/.local/share/pnpm,
~/.cache/ms-playwright) and persist between jobs without any
actions/cache plumbing. Switching cache: off avoids the zombie
retries and uses the local disk caches the runner already has warm.

Reviving the cache service is a separate TODO. Until then this is
the simpler and faster baseline.
