Closes #167

The Organization button on the Contribute screen links to a page that no longer exists (old project board), so it was removed.

• src/screens/Other/FeedbackScreen.tsx: removed the Organization button, only GitHub remains
• src/constants/Urls.tsx: removed feedback.project, unused elsewhere
• locales/fr.json, en.json, es.json: removed buttons.organization, unused elsewhere, and updated contributeDescription which mentioned the organization. it.json needed nothing (no buttons section)
