Refactor: Cardano node configuration in infra

[jpraynaud]

Content

This PR includes a refactoring of the Cardano node configuration in the infrastructure:

• It used to rely on the https://github.com/input-output-hk/cardano-configurations repository which is not well suited to handling edge case such as the co-existence of 8.9 and 8.12 as released version but running on different configurations.
• Configuration files are now retrieved from the source website: https://book.play.dev.cardano.org/.
• The new configuration supports the definition of patch or minor versions specific configurations which allows to now support the 8.12 configuration on the release-mainnet network.
• Also the deployments are now triggered when the aggregator or signer configuration is modified (Cardano version and/or node specific configuration parameters).
