Lua 5.5 support

[luau-project]

Hi,

in the current rockspec on LuaRocks website, there is a version gate preventing installation on Lua 5.5:

lua-path/rockspecs/lua-path-0.3.1-2.rockspec

Lines 16 to 19 in 5a32c70

	dependencies = {
	"lua >= 5.1, < 5.5",
	-- "luafilesystem >= 1.4",
	-- "alien >= 0.7.0", -- instead lfs on windows

Can lua-path be updated to work with Lua 5.5 and a new rockspec to be uploaded to LuaRocks website?
