Use this callback to know when the LinkControl component changes its mode to `edit` or `show`

### onSettingsChange

- Type: `Function`
- Required: No
- Args:
- `id` - the `id` property of the setting that changed (eg: `newTab`).
- `value` - the `checked` value of the control.
- `settings` - the current settings object.

Called when any of the settings supplied as `currentSettings` are changed/toggled. May be used to attribute a Block's `attributes` with the current state of the control.

```
<LinkControl
currentSettings={ [
{
id: 'opensInNewTab',
title: __( 'Open in New Tab' ),
checked: attributes.opensInNewTab, // Block attributes persist control state
},
] }
onSettingsChange={ ( setting, value ) => setAttributes( { [ setting ]: value } ) }
/>

I guess this was changed to avoid shadowing with the top-level prop? I'd typically not ever consider an abbreviation to be an improvement. I might have suggested something like nextValue if that's what it's intended to represent in this context.

If we don't have a link then we don't want to show this UI interface. Just curious as to why you feel it's safe to remove this now?

the boolean seemed explicit enough for me. If we do add the check for the value here, we should also add it to force showing the input if the value is empty which was not the case.
