Hlint restriction (and some other) settings not working

This differs from #1260 because even the `.hlint.yaml` file in the root of the workspace is not being used.

### Your environment

Which OS do you use:
ArchLinux, MacOS

Which LSP client (editor/plugin) do you use:
emacs+lsp-mode

Describe your project (alternative: link to the project):
GHC 8.10.7, cabal 3.6.2.0, hls 1.5.1, all installed with ghcup. hlint 3.3.4 installed with cabal.

A freshly initialized cabal project in a freshly initialized git repository with `.hlint.yaml` at the root of the repository:
```yaml
- functions:
- {name: nub, within: []}
```

### Steps to reproduce
Import and use `nub` in `src/MyLib.hs`. Running `hlint .` in the root of the repository emits a warning about the use of `nub`.

### Expected behaviour
The language server should also have a warning about the use of `nub`, as specified by the HLint configuration.

### Actual behaviour
No matter what is included in HLint configuration, the language server reports HLint warnings from the default HLint config and nothing else.

### Include debug information

Overwriting the `Hint` returned by `argsSettings` [here](https://github.com/haskell/haskell-language-server/blob/4386396624180de112d04335a75334d04781110c/plugins/hls-hlint-plugin/src/Ide/Plugin/Hlint.hs#L176) with `mempty` does remove all hints, so it seems that `argsSettings` isn't behaving as expected, which aligns with [this HLint issue](https://github.com/ndmitchell/hlint/issues/1232).
