Cardano Updates

Upgrade dependencies to 1.28.0

  The current CI workflow has a tendency to rebuild docker images fully, taking hours to complete. Instead, we can leverage the fact that the server also gets built as part of the workflow so that, instead of building it twice, we re-use the binary for the TypeScript tests. This changes a bit the way the TypeScript tests are executed since now, we need to run cardano-node as a separate container, with a real ogmios next to it.

  In particular:

  - `Tip` & `Point` have been renamed to `TipOrOrigin` and `PointOrOrigin`.
    As a consequence, `Tip1` and `Point1` are now simply `Tip` and `Point`.

  - Create a standalone definition for `Origin` and removed / replaced `Origin1`.

  - `SubmitTx` no-longer returns Byron errors. While this _is_ possible
    under some circumstances for privately set blockchain which would be
    running only the Byron era, it is not a use-case we're willing to
    support. Consequently, the TxSubmit errors are no-longer scoped
    under `errors.shelley` but simple `errors`.

  - Fixed `proposedProtocolParameters` query. All fields are actually
    required AND, more importantly, it can return either Shelley
    protocol parameters or, Alonzo protocol parameters.
