extensionPrefs: Simplify empty placeholder

GNOME Software will remove its extension support, so we should stop
referencing it in addition to extensions.gnome.org.

In fact, the placeholder is not the best place to hint at where new
extensions can be found, as the user will never see it in case the
distribution includes pre-installed extensions.

So remove the hint altogether, we will add it back in a more prominent
place later.

With the whole placeholder now being much lighter, we can stop dimming
the remaining elements.
