typos_lsp (potentially others): ignores root dir, when single_file_support = true

[kmoschcau]

Description

When I open a file with typos_lsp set up for it, typos_lsp always starts in single file mode, even though root_dir returns a file path. I can only get typos_lsp to run with a root_dir, when I explicitly set single_file_support to false.

local common = require "lsp.common"
local lspconfig = require "lspconfig"

lspconfig.typos_lsp.setup {
  root_dir = function(fname)
    local root = lspconfig.util.root_pattern(
      "typos.toml",
      "_typos.toml",
      ".typos.toml",
      "pyproject.toml"
    )(fname)

    print(root, type(root)) --> /home/kmoschcau/.config/nvim string

    return root
  end,
  single_file_support = false,
  capabilities = common.capabilities,
  handlers = common.handlers,
}

I only realized this, because typos_lsp does not take its config file into account, when it runs in single file mode.
