global config: move dom0 link to first paragraph in filecopy section

The 'Copying to and from dom0 is handled differently' link was
inside a GtkRadioButton which intercepted click events.
Move the link to the end of the intro paragraph where it is clickable regardless of radio button state.

Fixes QubesOS/qubes-issues#10743
