Reuse existing lsp

[ildar-shaymukhametov]

I have HLS LSP (for haskell) installed in .ghcup directory. This LSP is used by vscode (and by neovim before I installed Mason)
After installation of Mason, Neovim does not see this LSP anymore
I want to reuse this LSP for Nevim, I do not want to reinstall it again with Mason
Son how do I tell Mason to use that LSP?
