Offline Reports

Hi all,

I've just merged code to fwupd and deployed a new version of the LVFS
that allows generating and uploading a detached test report that can
be used when the test machine has no public internet connection.

When fwupd >=3D 1.9.11 is installed, the offline user can do:

    $ fwupdmgr install filename.cab
    =E2=80=A6reboot=E2=80=A6
    $ fwupdmgr report-export --sign
    $ cp *.fwupdreport /media/YOUR_USBDISK/

Then on a different [internet-connected] machine, log into the LVFS,
navigate to the specific firmware page and click the *Reports* tab.
From there the ``/media/YOUR_USBDISK/*.fwupdreport`` files can be
uploaded.

There's more details and a screenshot here:

It may be some time before some distros update to the
recently-released 1.9.11 version, but if it helps it's already
available for Fedora 39:

No action required, but I figured it might be helpful to some of you
struggling with the signed fwupd report requirement.
