Cardano Updates

Changed to public schema as network-specific schemas are no longer used.

Related additional changes:
- `SignedEntityTypeDiscriminants::all` exclude the new discriminant as
  it can't be derived without error right now which makes some tests
  fails
- Common `MithrilSignableBuilderService` will raise an error if the new
  type is ask
- Aggregator `MithrilSignedEntityService` will raise an error if the new
  type is ask
- Add migration in the signer and aggregator to add the new type in the
  `signed_entity_type` table

* mithril-persistence from `0.2.60` to `0.2.61`

* mithril-common from `0.6.41` to `0.6.42`
* mithril-signer from `0.3.3` to `0.3.4`
