Right (and leftonly) modifier (rshift, ralt, rctrl) support

[nixxou]

Shadowland and TBC have a bug where we can't use [rshift] and [lshift] macro (or rctrl, ralt...). But we can still bind direct action to them. For exemple, if in my config file hotkey i replace ["keys"] = { ["hotKeyText"] = ":cF2:", ["hotKeys"] = ":CTRL-F2:", },

by

						["keys"] = {
							["hotKeyText"] = ":cF2:",
							["hotKeys"] = ":RCTRL-F2:",
						},

My key will not only work with Right ctrl.

Can you add something that allow button to work with right (or left) modifier only ? Like an option on the bar for exemple ?
