An `AdwPreferencesGroup` represents a group or tightly related preferences,
which in turn are represented by [class@PreferencesRow].

To summarize the role of the preferences it gathers, a group can have both a
title and a description. The title will be used by [class@PreferencesWindow]
to let the user look for a preference.

## AdwPreferencesGroup as GtkBuildable

The `AdwPreferencesGroup` implementation of the [iface@Gtk.Buildable] interface
supports adding [class@PreferencesRow]s to the list by omitting "type". If "type"
is omitted and the widget isn't a [class@PreferencesRow] the child is added to
a box below the list.

When the "type" attribute of a child is `header-suffix`, the child
is set as the suffix on the end of the title and description.

## CSS nodes

`AdwPreferencesGroup` has a single CSS node with name `preferencesgroup`.

## Accessibility

`AdwPreferencesGroup` uses the `GTK_ACCESSIBLE_ROLE_GROUP` role.
