The fdroidserver repo hardcodes hashes of all gradle versions that are
allowed to be used. This is currently up to date, having 6.3. However,
the f-droid build server is not up to date, because it is controlled by
the founder of f-droid, who is generally unavailable and does not update
it. Meanwhile other members of the project would like to stand up their
own build server instance, but this seems potentially arduous and
there's still the question of the signing key. At least that's the story
I was able to glean from asking around.
So, in order to work around this organizational brokeness, we just
downgrade to 6.2.1.
