[PATCH 2/2] docs: make isa-debugcon example more useful / directly applicable

The type='pty' attribute in the <serial> element causes a Pseudo TTY to be allocated on the host side via "/dev/ptmx", which is meant to be interacted with via "virsh console" or similar. That's not how a firmware log is typically viewed or saved. Replace type='pty' with type='file', and also provide an example <source> element (with the pathname of the logfile), similarly to how the <serial> example just above provides a <source> element too.
