Why

We need to verify in the Mithril Client multi-platform test in the CI that the we can fast bootstrap a Cardano node with a ledger state that has been converted to LMDB flavor with the tools utxo-hd command of the client CLI.

What

Add a new step in the workflow which checks fast bootstrap of an LMDB UTxO-HD ledger state converted with the client CLI.

How

• Refactor the workflow to separate test of the cardano database v1/v2 download commands from the other commands
• Update the verify-cardano-db-restoration.sh script to allow to specify usage of a lmdb ledger state (use the CARDANO_CONFIG_JSON_MERGE env variable on the docker run to set the LedgerDB.backend parameter)
• Add a new matrix that run the conversion to lmdb then run the 'verify Cardano node starts successful' step
