Describe the bug

In mantine v6, <RichTextEditor.Toolbar> will render into a <Group> component internally and <Group> component has alignItems: center as the default.

In mantine v7, alignItems is not center any more by default, which is a UI break change for some case where the children controls of <RichTextEditor.Toolbar> has different heights.
