Cardano Updates

feat(docs): add test results for node tag 10.4.1

fix(utxo-hd): each testnet instance need unique lmdb path

Introduce `LIVE_TABLES_PATH` variable to specify the path for live tables
when using the `disk` backend. Update configuration to include the
`LedgerDB.LiveTablesPath` field for the `disk` backend. Ensure the path
is created if it does not exist.

feat(workflows): add empty option for UTxO backend choice

Added an empty string option to the UTxO backend choice in both
`regression-dbsync.yaml` and `regression.yaml` workflows. This ensures
that users can explicitly select no backend if needed.

feat(workflows): add utxo_backend input to workflows

Added a new input parameter `utxo_backend` to the regression workflows
(`regression-dbsync.yaml`, `regression.yaml`, and
`regression_reusable.yaml`). This parameter allows specifying the UTxO
backend with options `mem` or `disk`.

feat(utxo-hd): update UTXO backend configuration

The UTXO backend configuration now happens in node config.

Updated jq commands to dynamically set `LedgerDB.Backend` based on
the backend type (`mem`, `disk`) or remove it if not applicable.

feat(submit-api): improve retry logic and timeout handling

- Increased HTTP request timeout from 20 to 60 seconds.
- Simplified retry logic by removing unnecessary delay flag.
- Added a final error raise if all attempts fail to submit the transaction.

These changes enhance the robustness of transaction submission by
providing better retry handling and clearer error reporting.

fix(utils): update GitHub auth method for token usage

Updated the GitHub authentication method to use `github.Auth.Token`
when a token is provided. This ensures compatibility with the latest
GitHub API changes.
