UX: Display setting description for objects typed theme setting (#26152)

Why this change?

Prior to this change, there is no description being displayed for
objects typed theme setting because we were rendering a button instead
of the components for the various setting types which will render the
setting's description.

What does this change do?

1. Introduce `SiteSettings::Description` compoment to centralise the HTML
being rendered across all settings component.

2. Renders the `SiteSettings::Description` component after the edit
   button in `site_setting.hbs`.
