Is your feature request related to a problem? Please describe.

In the example it opens all the todo comments in the project.

{
  "folke/todo-comments.nvim",
  optional = true,
  keys = {
    { "<leader>st", function() Snacks.picker.todo_comments() end, desc = "Todo" },
    { "<leader>sT", function () Snacks.picker.todo_comments({ keywords = { "TODO", "FIX", "FIXME" } }) end, desc = "Todo/Fix/Fixme" },
  },
}

Describe the solution you'd like

An argument to Snacks.picker.todo_comments() to show todos in the current file only.

Describe alternatives you've considered

Grep for TODO comments.
