`Cardano.Ledger.Shelley.API.Types` keeps re-exporting the deprecated
`Shelley*` rule names (sourced from `Cardano.Ledger.Shelley.Era`) rather
than the new ones, since this module will eventually be removed. Update
the internal call sites to import the new rule names from
`Cardano.Ledger.Shelley.Rules` directly.
