test: add client-cache.defaults failing deploy test (#89242)
This deployment test has been failing very recently since the first
attempt of
[v16.1.5](https://github.com/vercel/next.js/actions/runs/21373599266/attempts/2).
Tried deflaking at https://github.com/vercel/next.js/pull/87412, but
seems to have no effect. This PR adds the test case to the deployment
test manifest to unblock sync. Will continue deflaking at this PR at
https://github.com/vercel/next.js/pull/89106
