[GNC] Flatpak updates

[Geert Janssens]

Hi,

I have just landed Finance::Quote support in our gnucash flatpak packages. From a 
user point of view all that has to be done to make it working is to either install the most 
recent version or upgrade to it.

If your linux distribution has built-in flatpak support you can use your package manager 
to get the most recent release, otherwise you can find more info on installing flatpaks 
here:
https://wiki.gnucash.org/wiki/Flatpak

The package on flathub should be available in a few hours from now, our nightly build 
repository will provide it as of tomorrow.

If you experience any issues please let us know.

Enjoy!

Geert
