Update cabal-helper to version 0.8.1.2 that supports Cabal (>=1.14 && <1.26 || >=2.0 && <2.5)

Building cabal-helper-0.8.1.2 with Stack failed with 'Dependency cycle detected' error. It seems to be https://github.com/commercialhaskell/stack/issues/4265 Stack bug. As a temporary solution I added source code of cabal-helper package to vendor directory and commented out 'build-tool-depends:  cabal-helper:cabal-helper-wrapper' line in the cabal-helper.cabal file.
