The haddock comment in stack-templates is broken and HLS cannot be enabled by default

[ncaq]

This issue is related to the following repository issues
The README says that the issue should be written here, so I am building the issue here.

yesodweb/stack-templates: Yesod's scaffoldings, for use with the stack new command

Reproduction steps.

Enable the following settings in the configuration file

~/.stack/config.yaml

# for [haskell-language-server](https://github.com/haskell/haskell-language-server)
ghc-options:
  "$everything": -haddock

Do it.

stack new postgres-project yesodweb/postgres
cd postgres-project
stack test --no-run-tests

error.
