fix(index): remove stale castrojo/jorgehub/* entries from Flatpak remote index

These entries were created by running 'just update-index' without --repo,
which used the wrong default path castrojo/jorgehub/<app> instead of
castrojo/<app>. The correct entries already exist at castrojo/<app>.
Stale entries caused flatpak client to match wrong registry path -> silent 404.

Also adds missing goose and firefox-nightly entries from previous session
work that was never committed.
