Smart copy info widget: provide alternative to tooltips for viewing information
Problem
Code currently has a widget next to the "Smart cut/copy lines:" option explaining this option in more detail: https://github.com/elementary/code/blob/ceb3b1f34f6ab4d8ea242c0c46e5a126d48846f8/src/Dialogs/PreferencesDialog.vala#L46-L48 This additional information can currently only be viewed by hovering over this widget, meaning that if the user isn't using a mouse/touchpad this information cannot be viewed.
