feat: add a better scroll behave on playground's chat (langflow-ai#3680)

* feat: Add useUtilityStore hook to IOModal for setting playground scroll behavior

* feat: Add useUtilityStore hook to IOModal for setting playground scroll behavior

* feat: Add setPlaygroundScrollBehaves function to useUtilityStore hook

* feat: Update codeTabsPropsType to allow undefined for the 'open' property

* feat: Add `playgroundScrollBehaves` and `setPlaygroundScrollBehaves` to `UtilityStoreType`

The `UtilityStoreType` now includes the `playgroundScrollBehaves` property of type `ScrollBehavior` and the `setPlaygroundScrollBehaves` function to update it. This allows for managing the scroll behavior of the playground in the application.

* refactor: Remove unused 'open' prop from CodeTabsComponent
