bisq-desktop: mark as broken

OpenJFX 11 has been EOL for over a year; upstream
uses OpenJFX 15 which is also EOL. According
to <bisq-network/bisq#6758>, the
application does not function with later versions, and has a
limited remaining lifespan as there is a new major version that
uses more modern versions. It looks like that version officially
supports OpenJDK 22, which is also EOL, but hopefully it will
work with 21 or 23. Some work was done already to package it here:
<NixOS#318594>.
