turn-on-haskell-indent doesn't work

I prefer behaviour of haskell-indent-mode since I like to use it to repate function name between type anotation and implementation.

Following manual for haskell-mode https://haskell.github.io/haskell-mode/manual/latest/Indentation.html

I tried to add:

```el
(add-hook 'haskell-mode-hook 'turn-on-haskell-indent)
```

into configuration but it doesn't seem to have an effect.

When I open a .hs file, haskell-mode is enabled but I still see `haskell-indentiation-mode` is used and I need to manually start `haskell-indent-mode`.

I did not (yet) find any way how to realiably add haskell-indent-mode onto haskelll-mode-hook yet so I have no workaround.

Start with the haskell-mode-hook setup described in the issue and inspect how turn-on-haskell-indent relates to haskell-indent-mode and haskell-indentation-mode. Reproduce the behavior by opening a .hs file, then verify that the configured hook activates haskell-indent-mode without manual intervention.
