Scala 3: Completions, HOFs and aliased tuple types

[kubukoz]

Describe the bug

To reproduce:

1. Write this

   
   //> using scala 3.5.0-RC5
   trait Foo {
   def setup: List[Foo.Result]
   }

object Foo { type Result = (String, String)

def demo(foo: Foo) = { foo.setup.map }

}

2. Get completions at `<cursor>`
3. See this:

### Expected behavior

- No parenthesis around `Result`
- Wouldn't mind seeing the type alias's enclosing type name (`Foo.Result`) like in Scala 2

### Operating system

macOS

### Editor/Extension

VS Code

### Version of Metals

v1.3.3

### Extra context or search terms

- This is a really minor issue, arguably a cosmetic
- Opaque types don't have the parenthesis

Thanks for reporting! Looks like the first picture didn't upload, but I guess this about the added () around Foo.Result?

The type alias changes might have not been ported yet to Scala 3 repo.

Yes, sorry, I didn't notice after posting 😅 the completion in Scala 3 shows "(Result)" where 2.13 shows "Foo.Result".
