Previously, if an app version contained the same files as an older version (e.g. making a change, then rolling it back), the SW would not detect it as the latest version (and update clients). This commit fixes it by adding a `timestamp` field in `ngsw.json`, which makes each build unique (with sufficiently high probability). Fixes #24338 PR Close #26006
