`hls-hlint-plugin` test failure in Gentoo Linux

I'm getting a test failure for `hls-hlint-plugin-1.1.0.0`:

```
.hlint.yaml fixity rules are applied: FAIL (8.52s)
src/Test/Hls/Util.hs:308:
Got unexpected diagnostics for Uri {getUri = "file:///var/tmp/portage/dev-haskell/hls-hlint-plugin-1.1.0.0/work/hls-hlint-plugin-1.1.0.0/test/testdata/fixity/FixityUse.hs"} got [Diagnostic {_range = Range {_start = Position {_line = 5, _character = 13}, _end = Position {_line = 5, _character = 46}}, _severity = Just DsInfo, _code = Just (InR "refact:Functor law"), _source = Just "hlint", _message = "Functor law\nFound:\n show <$> mInt pure <$> Just c\nWhy not:\n show . (mInt pure) <$> Just c\n", _tags = Nothing, _relatedInformation = Nothing}]
Use -p '/.hlint.yaml fixity rules are applied/' to rerun this test only.
```

Here is the diagnostic message pretty-printed:

```haskell
[ Diagnostic
{ _range = Range
{ _start = Position
{ _line = 5
, _character = 13
}
, _end = Position
{ _line = 5
, _character = 46
}
}
, _severity = Just DsInfo
, _code = Just
( InR "refact:Functor law" )
, _source = Just "hlint"
, _message = "Functor law
Found:
show <$> mInt pure <$> Just c
Why not:
show . (mInt pure) <$> Just c
"
, _tags = Nothing
, _relatedInformation = Nothing
}
]
```

### Your environment

- GHC 9.0.2 on Gentoo Linux. All packages are installed through the system package manager.
- HLint v3.4.1

This seems to be unrelated to [my other issue](https://github.com/haskell/haskell-language-server/issues/3126), as I am getting this failure when I run the tests outside Gentoo's sandbox, so it seems to be unrelated to any sandboxing issues.
