0.6 Migration guide and documentation

[TimoGlastra]

• Supported versions
  • Minimum supported React Native version?
    • In React Native (if you're below 0.79) you must enable https://metrobundler.dev/docs/package-exports/
    • I think mostly dependent on Askar/AnonCreds/IndyVDR
    • Animo: expo: 53.0.13 / react-native: 0.79.4
    • Newest is 0.82, so can target e.g. 0.79 through 0.82 (expo 53 and 54)
  • Node.JS versions: 20 and 22
