Describe Your Changes

This adds a new option for the Link toolbar icon/popup to disable the "Open in new tab" option from showing in the UI, for i.e. a Markdown serializer where target is not supported. Specifying "link" as a ToolbarItem is still supported and the default is to show the "Open in new tab" option, but you can now pass an object instead to specify its options via { link: { showOpenInNewTab: false } }, similar to the heading toolbar item.
