Redundant keyword arguments passing in client.dynamic

[junkmd]

THIS IS FOR drop_py2 PLAN! Please see #392.

The following code instantiates a dictionary from the dict class, unpacks it, and passes it to the method as keyworded arguments.

comtypes/comtypes/client/dynamic.py

Lines 47 to 64 in 22bfc50

	def __getitem__(self, *args):
	return self._obj._comobj.Invoke(
	self._id, *args, **dict(_invkind=comtypes.automation.DISPATCH_PROPERTYGET)
	)
	def __setitem__(self, *args):
	if _is_object(args[-1]):
	self._obj._comobj.Invoke(
	self._id,
	*args,
	**dict(_invkind=comtypes.automation.DISPATCH_PROPERTYPUTREF)
	)
	else:
	self._obj._comobj.Invoke(
	self._id,
	*args,
	**dict(_invkind=comtypes.automation.DISPATCH_PROPERTYPUT)
	)

Modernizing this code would allow it to fit on fewer lines.

I created this issue to serve as a "model case" for future good first issue that I will submit.

I will work on this.
