Polkadot Upgrade

We are currently using Substrate version polkadot-v0.9.42. The latest available version is polkadot-v1.5.0, and ParityTech has recently undergone significant repository reorganization. It would be advantageous for us to upgrade to at least to the 1.0 version era.

To-do List:

On GitHub, rebase/replace the old repository with our fork of polkadot-sdk.
Cherry-pick our custom commits (4 commits).
Update Substrate in the duniter-v2s repository.
Rewrite the benchmarks using the v2 syntax.
