wrong default align in resample_spatial

[soxofaan]

(Stumbled on this while working on Open-EO/openeo-python-client#690)

openeo-python-driver/openeo_driver/ProcessGraphDeserializer.py

Lines 1583 to 1589 in d4c4d71

	def resample_spatial(args: ProcessArgs, env: EvalEnv) -> DriverDataCube:
	cube: DriverDataCube = args.get_required("data", expected_type=DriverDataCube)
	resolution = args.get_optional("resolution", 0)
	projection = args.get_optional("projection", None)
	method = args.get_optional("method", "near")
	align = args.get_optional("align", "lower-left")
	return cube.resample_spatial(resolution=resolution, projection=projection, method=method, align=align)

Here we use default "lower-left" for align parameter

official resample_spatial spec specifies default "upper-left" for align

turns out the align value is not used yet (e.g see https://github.com/Open-EO/openeo-geopyspark-driver/blob/69b1b46b097f1c208652d8c650485091bbd96c2d/openeogeotrellis/geopysparkdatacube.py#L1297) so we can just update the default without much worries
