Changing `pac_onuse_only` calls nonexistent typo hook name instead of real hook

[TiberiumFusion]

This is a case of a typo + a footgun.

show_outfit_on_use.lua :: pace.OnUseOnlyUpdates() does this: pace.Call("OnUseOnlyUpdates", ...)

pac3/lua/pac3/editor/client/show_outfit_on_use.lua

Lines 74 to 76 in ad24088

	function pace.OnUseOnlyUpdates(cvar, ...)
	pace.Call("OnUseOnlyUpdates", ...)
	end

and then editor/client/init.lua :: pace.Call() prefixes that "OnUseOnlyUpdates" with "On" and then tries to call nonexistent hook "OnOnUseOnlyUpdates", resulting in the actual hook failing to run and the user getting a scary Lua error popup. This is a pretty bad look for simply toggling the most popular pac user preference.

pac3/lua/pac3/editor/client/init.lua

Lines 298 to 306 in ad24088

	function pace.Call(str, ...)
	if pace["On" .. str] then
	if hook.Run("pace_On" .. str, ...) ~= false then
	return pace["On" .. str](...)
	end
	else
	ErrorNoHalt("missing function pace.On" .. str .. "!\n")
	end
	end

In addition to fixing this, I recommend fixing pac's footgun of prefixing of hook names like this and requiring the caller to omit the known prefix.
