This commit also performs lock file maintenance on all integration
tests, fixing some ambigous ESM/CJS dependency graph issues.
e.g.
```
Unknown error: Error [ERR_REQUIRE_ESM]: require() of ES Module /tmp/ng-integration-test-aTpQOT/test-sandbox/node_modules/string-width/index.js from /tmp/ng-integration-test-aTpQOT/test-sandbox/node_modules/cliui/build/index.cjs not supported.
Instead change the require of index.js in /tmp/ng-integration-test-aTpQOT/test-sandbox/node_modules/cliui/build/index.cjs to a dynamic import() which is available in all CommonJS modules.
