Remove extra lines when displaying helper or error text for custom params and hide the copy option from custom params modal when no params are available

[ymaheshwari1]

Current behavior

• When displaying helperText or errorText for custom parameters, a separate line gets displayed for the helper/error text.
• If there are no custom params available then the copy button on the custom params modal should not be displayed as only an {} object is copied and there is no use case for having the button when there is no data inside the modal.

Expected behavior

• Only display a single line for custom params and remove the duplicate line
• Remove the copy icon from the modal when there is no data to copy inside the custom params modal

Issue verified in release v2.23.0 and found that issue is still there as no line is visible in between the optional custom parameters as seperator. https://jam.dev/c/f962d025-73f8-4ea8-a4b5-610b86da47ab
