_ZL_FZF_HEIGHT does not work on windows

[SMUsamaShah]

z -I . was clearing my whole terminal. This turned out to be missing --height parameter from fzf.

I found this section and few other similar ones not including --height param when its windows.

		if not windows then
			tmpname = os.tmpname()
			local height = os.environ('_ZL_FZF_HEIGHT', '35%')
			if height ~= nil and height ~= '' and height ~= '0' then
				cmd = cmd .. ' --height ' .. height
			end
			cmd = cmd .. ' < "' .. tmpname .. '"'
		else
			tmpname = os.tmpname():gsub('[\\:]', ''):gsub('%.', '')
			tmpname = os.environ('TMP', '') .. '\\zlua_' .. tmpname .. '.txt'
			cmd = 'type "' .. tmpname .. '" | ' .. cmd
		end

fixed in https://github.com/skywind3000/z.lua/releases/tag/1.8.22

Because fzf didn't support --height on windows at the beginning.
