fix: missing argument for nvim_tabpage_list_wins

[jaspreetpanesar]

Hey there!

This is fixing the following plugin crash which occurs for me after opening then closing window splits. Function nvim_tabpage_list_wins looks to require at least one argument

Error executing vim.schedule lua callback: .../fidget.nvim/lua/fidget/poll.lua:119: .../fidg
et.nvim/lua/fidget/notification/window.lua:182: .../fidget.nvim/lua/fidget/notification/window.lua:193: Expected 1 a
