Update editor setup docs about Neovim and Vim

[otakutyrant]

Summary

I struggled to make ruff_organize_imports work and then I found out I missed the key note about conform.nvim before because it was put in the Vim section wrongly! So I refined them both.

Thank you! I made a couple of edits mainly around rearranging the ALE plugin section.

FWIW 3rd party plugins are not required, native LSP works as well with a config like this:

local ms = vim.lsp.protocol.Methods
vim.lsp.config("ruff", {
  on_attach = function(client, bufnr)
    -- Set a keymap to both ruff fix and ruff format
    vim.keymap.set("n", "<Leader>f", function()
      client:request_sync(ms.workspace_executeCommand, {
        command = "ruff.applyAutofix",
        arguments = { { uri = vim.uri_from_bufnr(bufnr), version = vim.lsp.util.buf_versions[bufnr] } },
      }, 1000, bufnr)
      vim.lsp.buf.format({
        async = true,
        bufnr = bufnr,
        id = client.id,
      })
    end, { buffer = bufnr, desc = "Format buffer with ruff" })
  end,
} --[[@as vim.lsp.Config]])
