Code Review

This pull request updates several cross-repository Angular dependencies, as indicated by the title and description. The changes involve updating commit hashes for @angular/ng-dev in package.json and devinfra in MODULE.bazel. The modifications in pnpm-lock.yaml are consequential, reflecting the updated dependency tree from these changes. The pull request appears to be a routine dependency maintenance task, and the changes are consistent with this goal.
