Show function argument documentation in hovers

I'd loved to see those function "signature comments" displayed. HLS already helps to write them. I found them often being a true way of documenting what function does, as people often in function docs just white what functions accepts & does with args - people write that style way quite intuitively & that fits greatly to be a signature comments. To see those sometimes would be an immense simplification to read code.

Several years ago - I remember the dialog that Haddock-like signature comments were not yet in the LSP protocol specification.

What is the current status there (and here 8) )?


As I arrived though reading `lsp-haskell` -> `lsp-ui` -> `lsp-mode` -> searching though `HLS` & looking at `Microsoft LSP specs` and seeing there as good as :bat: :dark_sunglasses: :sunglasses: :night_with_stars: :wavy_dash: :crescent_moon: :wavy_dash: & in that way I arrived here. & decided you should know something about what are the current affairs there 8)
