Update firmware text

The software image at the top of the table (i.e. the one with
the highest priority) is used the next time the device is
booted. Update the text to reflect this.
More information on Priority can be found here:

github.com/openbmc/phosphor-dbus-interfaces/blob/master/xyz/openbmc_project/Software/RedundancyPriority.interface.yaml

Tested: Verified I see the text.
