Describe the bug
The current Haskell command uses the interpreter runghc for execution, which is slower compared to using the compiler ghc. This update proposes changing the command to use ghc for faster execution.

To Reproduce
Steps to reproduce the behavior:

1. Use the current Haskell command with runghc.
2. Observe the execution time.
3. Update the command to use ghc as proposed.
4. Observe the reduced execution time.

Actual behavior
The Haskell scripts execute slower using the interpreter runghc.

Expected behavior
The Haskell scripts should execute faster using the compiler ghc.

Proposed Command:

"haskell": "ghc -outputdir ./build -o \"$dir$fileNameWithoutExt\" \"$fileName\" && if ($?) { & \"$dir$fileNameWithoutExt\" }"
