code actions break literate haskell (lhs) files

### Your environment

Debian stable, HLS 1.6.1.0, the problem happens with **emacs+lsp-mode**, and **VS Codium+vscode-haskell**

(Hence I report it here and not to the editor plugins, hope that makes sense.)

### Steps to reproduce

1. Create a literate Haskell file `foo.lhs` with this content:

```
This is a comment.

> module Main where
>
> main = putStrLn ("Hello")
```

2. Note that two code actions are provided, one to add the type signature for `main` and one to remove the redundant bracket.

3. Apply either of the two code actions.

### Expected behaviour

Applying the two code actions should only modify code within the `> ` blocks and not change or remove comments.

For the type signature we want this result:

```
This is a comment.

> module Main where
>
> main :: IO ()
> main = putStrLn ("Hello")
```

For the brackets we want:

```
This is a comment.

> module Main where
>
> main = putStrLn "Hello"
```

### Actual behaviour

Both code actions "break" the file.

The type signature is added without a `> ` prefix, so it will be a comment and not seen as Haskell code. Moreover, empty lines are needed to separate code from comments, so `unlit` fails after the change is made:

```
This is a comment.

> module Main where
>
main :: IO ()
> main = putStrLn ("Hello")
```

Curiously, applying the hlint code action to remove the brackets works, but it also deletes all `> ` and all comments from the file:

```

module Main where

main = putStrLn "Hello"
```

Is there a way to fix this? From https://github.com/haskell/ghcide/commit/44b11667d8593ae84c48ca88e96f4f227deec096 I understand that haskell-language-server uses the `unlit` stage from ghc and then only looks at the resulting code, so it might be hard or even impossible to get the expected behavior above?
