Update dependencies.

- cardano-ledger-specs has been reorganised for sanity.
  (IntersectMBO/cardano-ledger#2483)
  This entails a number of refactorings:
  - The package 'shelley-spec-ledger' is now deprecated in favour of
    'cardano-ledger-shelley'.
  - Shelley.Spec.NonIntegral -> Cardano.Ledger.NonIntegral
  - Shelley.Spec.Ledger -> Cardano.Ledger.Shelley
  - *.STS -> *.Rules
  - Test.Shelley.Spec.Ledger -> Test.Cardano.Ledger.Shelley

- As per IntersectMBO/ouroboros-network#3369,
  there is now no 'FilePath' argument to 'localSnocket'.

- Bump base to include a potential memory leak fix.
