Configure LSP command through vim.lsp.config

[sjcobb2022]

Feature description

Currently if one does not provide a cmd to vim.g.haskell_tools.hls.cmd HLS does not auto start.

I do not have haskell-language-server in my PATH (nixos) but I have configured it via vim.lsp.config.

I assumed given the phrasing in the README, I could set up HLS purely through vim.lsp.config including commands.

I believe https://github.com/mrcjkb/haskell-tools.nvim/blob/76e286150ef2c6e4d8ff479bbf026067f3c90b3f/lua/haskell-tools/config/internal.lua#L116C4-L126C17 should be updated to reflect what is configured in vim.lsp.config as well. This is already done in

haskell-tools.nvim/lua/haskell-tools/lsp/init.lua

Line 110 in 76e2861

Hls.start = function(bufnr)

I personally don't have a need for this, so I won't treat this as high priority. But PRs are welcome 😄
