Improve link field behaviour - change icon, confirm field when user presses Enter

[rinart73]

I'm using Kadence Blocks for several months and I just randomly realised that custom links are not Pro feature. You need to press the button with an icon that looks like a "revert". It's especially confusing since pressing Enter key doesn't confirm the link either.

So my suggestion is:

• Change the icon of the link submit button to something less confusing
• When user presses Enter treat it like the submit button was pressed

It seems I'm not the only one who was confused:
