fix: update node alert to detect outdated components (langflow-ai#3051)

* check nodes to update on build flow

* feat: update componentsToUpdate logic in flowStore.ts

The `updateComponentsToUpdate` function in `flowStore.ts` has been updated to properly check for outdated nodes. This ensures that components are only updated when necessary, improving performance and preventing unnecessary re-renders.

* [autofix.ci] apply automated fixes

* Update src/frontend/src/stores/flowStore.ts
