* test(e2e): fix failures due to latest and canary releases

[v14.2.10](https://github.com/vercel/next.js/releases/tag/v14.2.10) and
[v15.0.0-canary.147](https://github.com/vercel/next.js/releases/tag/v15.0.0-canary.147) included
vercel/next.js#69802 which added `private` back into `no-cache,no-store`
`cache-control` headers in some cases.

* fix: fix private directive logic in tests

* test: update one more no-cache test
