This PR adds new tokens in mainnet

TODO to finish this PR

• [x] Get tokens / pool addresses
• [x] Check if we need to add testnet conf
• [x] Put archethic-dapp-framework-flutter new version in pubspec (cf https://github.com/archethic-foundation/archethic-dapp-framework-flutter/pull/21)
• [x] Finish lib/domain/repositories/pools.json conf (cf https://github.com/archethic-foundation/bridge/pull/147/files)
• [x] Finish lib/domain/repositories/tokens_list_per_bridge.json conf (cf https://github.com/archethic-foundation/bridge/pull/147/files)

In a future pull request, the addition of a new token will be directly onchain. This harcoded addition is for current short-term needs.
