Typo in GpChatToggle

[myarcana]

While working on #234, I noticed this surprise

I guess this ~= in ChatToggle should be a == instead

gp.nvim/lua/gp/init.lua

Lines 855 to 857 in 2372d53

	-- if the range is 2, we want to create a new chat file with the selection
	if params.range ~= 2 then
	local last = M._state.last_chat
