    Deprecate `shelleyCertificateConstraints` and `conwayCertificateConstraints`
  compatibility: breaking
  type: feature

Context

shelleyToBabbageEraConstraints already provides all the constraints that shelleyCertificateConstraints.

conwayEraOnwardsConstraints already provides all the constraints that conwayCertificateConstraints.

Deprecating these functions will reduce the size of the API.

Going forward, when needing constraints for ShelleyToBabbageEra, one only need to use shelleyToBabbageEraConstraints.

Going forward, when needing constraints for ConwayEraOnwards, one only need to use conwayCertificateConstraints.

If more constraints are needed then those constraints can be added to shelleyCertificateConstraints and conwayCertificateConstraints.

Strangely ETA reduction doesn't work.

Not an issue for these functions are planned for deletion anyway

Why not ShelleyLedgerEra era ~ ledgerera? It would be a little bit more readable imo.
