fix(get_win): typing of the `get_win()` fn `win` param

[Masstronaut]

Description

vim.api.nvim_get_current_win() and vim.api.nvim_list_wins() return integer and integer[], respectively. Integer seems to be the correct typing annotation here. Similarly, edgebar.wins.win is a window ID integer, so the final conditional of this function is comparing the win param to an integer.
