feat: added a new widget for the default_worker_pool_machine_type variable to enhance the user experience<br> - The widget dynamically fetches available worker node flavors based on the selected region, ensuring users only see machine types that are actually available in their chosen deployment location. (#863)

* added the worker node flavour widget

* updated the description

* small fix

* removed the default_value field

* removed additional fields

* validation

* reverting for cross check
