docs(README): telescope remove selected item

[sand4rt]

Thanks for the awesome plugin!

I derived the code telescope git branch picker:
https://github.com/nvim-telescope/telescope.nvim/blob/dfa230be84a044e7f546a6c2b0a403c739732b86/lua/telescope/builtin/__git.lua#L335-L361

There is one bug that was unable fix tho. It seems that the harpoon:list():get(selection.index) is not getting the correct hapoon item. Any idea how to fix this?

Is it also possible swap/rearrange harpoon list items in telescope with a keymap BTW? Maybe I can put that in the docs too?

there is some integration https://github.com/soramon0/kickstart.nvim/blob/6858e7bf6b4daa0bd9f4685d80dbfd764a895692/lua/sora/plugins/harpoon.lua#L35

    -- basic telescope configuration
    local conf = require('telescope.config').values
    local function toggle_telescope(harpoon_files)
      require('telescope.pickers')
        .new({}, {
          prompt_title = 'Harpoon',
          finder = make_finder(harpoon_files),
          previewer = conf.file_previewer {},
          sorter = conf.generic_sorter {},
          attach_mappings = function(bufnr, map)
            map('i', '<C-d>', function()
              local state = require 'telescope.actions.state'
              local selected_query = state.get_selected_entry()
              local current_picker = state.get_current_picker(bufnr)
              harpoon:list():remove_at(selected_query.index)
              current_picker:refresh(make_finder(harpoon:list()))
            end)

            return true
          end,
        })
        :find()
    end

I am using my own Remove instead of remove from harpoon2:

local opts = { noremap = true, silent = true }
local harpoon = require("harpoon")
local list = harpoon:list()

function Remove(item)
  item = item or list.config.create_list_item(list.config)
  print("Hello")
  local Extensions = require("harpoon.extensions")
  local Logger = require("harpoon.logger")

  local items = list.items
  if item ~= nil then
    for i = 1, list._length do
      local v = items[i]
      print(vim.inspect(v))
      if list.config.equals(v, item) then
        -- this clears list somehow
        -- items[i] = nil
        table.remove(items, i)
        list._length = list._length - 1

        Logger:log("HarpoonList:remove", { item = item, index = i })

        Extensions.extensions:emit(
          Extensions.event_names.REMOVE,
          { list = list, item = item, idx = i }
        )
        break
      end
    end
  end
end
