Support for stack scripts

[fyusuf-a]

It is possible to execute a stack program outside of a stack project and with only one file using the lines provided in the documentation. Would it be possible to implement support for this in your project ?

Your environment

Output of haskell-language-server --probe-tools or haskell-language-server-wrapper --probe-tools:

Describe your project (alternative: link to the project):

Content of Main.hs :

#!/usr/bin/env stack
-- stack script --resolver lts-12.21 --package async

import Control.Concurrent.Async
import Data.Foldable (traverse_)

main = undefined

Steps to reproduce

chmod +x Main.hs
./Main.hs

Expected behaviour

No linting for errors should happen.

Actual behaviour

The haskell-language-server should report no error.
