commit 125f68a9093f82abb4ab085747d4271bcd95076c

    template-haskell: Drop use of Rank2Types/PolymorphicComponents
    
    As per #6032, `Rank2Types` and `PolymorphicComponents` have been
    deprecated in favour of `RankNTypes`.
    
    also update `other-extensions` in template-haskell.cabal flag to
    reflect reality.
    
    (cherry picked from commit 1a9734a69260e69943c00755952edd7185dcc484)
