[GNC] Update F::Q in flatpak GC?

[rsbrux]

I am running GC 5.3+ as a flatpak under Ubuntu  Studio 22.04 LTS.

The included F::Q version is 1..56, which I have modified with the Yahoo 
as JSON patch already published to this mailing list.

However, it looks as though the current F::Q release, 1.58, includes 
quite a few fixes for various sources.

The last I heard,  it wasn't possible to update F::Q within a flatpak 
installation of GC.  Is that still the case?

If so, when can a flatpak update of GC containing F::Q 1.58 be expected?

If not, how can I update F::Q within my flatpak installation?
