[FEAT] Add InputPicker for InputUIHints

[Angus221]

Feature Request

Description: I would like to request the addition of an InputPicker to complement the existing VariablePicker and OutputPicker. This new InputPicker would allow users to easily select and pass workflow input parameters directly to specific activities.

Current Situation: Currently, we only have VariablePicker and OutputPicker, which are useful for accessing variables and output values from workflow. However, there is no straightforward way to select and use input parameters that were initially passed into the workflow.

Proposed Solution:

Introduce an InputPicker option in the activity editor UI. This InputPicker would provide a quick way for users to select from the initial workflow input parameters. Once selected, the input parameter would be automatically set as the input for the activity, simplifying the process of passing workflow inputs to specific activities. Benefits:

Streamlines workflow configuration by reducing the need to manually type input parameter references. Enhances the flexibility and usability of the workflow designer, especially for workflows that rely on external inputs. Reduces the risk of errors by providing a consistent way to access workflow inputs. Thank you for considering this feature request!

I think that's a great idea and we should implement it. Thanks!
