Fix webhook callback url in copy curl

[wintonzheng]

[!IMPORTANT] Fix handling of webhookCallbackUrl in RunWorkflowForm to ensure correct inclusion in requests and cURL commands.

• Behavior:
  • In RunWorkflowForm, separate webhookCallbackUrl from other parameters in onSubmit() and onClick() to ensure it's included correctly in the request body.
  • Update fetchToCurl call to include webhookCallbackUrl if present.
• Functions:
  • Modify onSubmit() and onClick() in RunWorkflowForm.tsx to handle webhookCallbackUrl separately from other parameters.
