Feature/banana

[arnaubennassar]

• Refactor to use contracts from cdk-contrats-tooling
• Add new endpoint to support banana signature schema
• Remove integration test as it will happen on the main CDK repo

⚠️ The code of the PR is done, however, waiting on sequence sender to be updated so we can have the full E2E test using the new endpoint and check that this actually works
