gnu: Update Haskell ecosystem.
Bump packages’ versions to the lastest Stackage or Hackage
release. Since packages are interdependent, do so in a single commit.

525 packages have been updated.

These packages have been removed, because they fail to build, have no
newer version available and no dependencies:

corrode
ghc-easytest
ghc-edisonapi
ghc-edisoncore
ghc-pandoc-types
ghc-regex-tdfa-text

These have been removed, because they are no longer required:

ghc-happy-1.19.9
ghc-prettyprinter-1.6
ghc-protolude-0.3

ghc-pandoc-citeproc and pandoc-citeproc have been removed, because pandoc
does not use them any more.
