FGAddon: pa38 added to /branches/release-2024.1 but not to trunk?

Hello,

I just noticed a new and excellent addition to FGAddon, namely the Piper
PA-38 Tomahawk by awall86.  Thanks for this!  However, this aircraft is
available only in the 2024.1 branch and not on trunk.  This might not
look like a problem but, right now, people using next or any past
release of FlightGear cannot see this aircraft in the launcher.
Furthermore, when the a new version of FlightGear is released and a new
branch is created in FGAddon, the Tomahawk will disappear from the
launcher for people migrating from 2024.1.

The recommended way to develop aircraft in FGAddon is to to this in
trunk and optionally to merge (backport) to release branches, as
described in [1].

I'm unsure what to do.  I could do a one-off merge myself, or I could
provide guidance (if and as required) for repeated merges but
ultimately, awall86 should decide on the preferred workflow.  There is
no urgency to do anything, obviously, as the real problem will only
become visible the next time a release branch is created.
