Add IZeroClampSeries and RoiResponseSeries to the neurodata type map; fix OptogeneticStimulusSite typo

[bendichter]

process_ndtypes drops any neurodata type that isn't a key in neurodata_typemap, so types missing from the map contribute nothing to an asset's variableMeasured, measurementTechnique or approach. This fills two gaps and fixes a typo:

• IZeroClampSeries (icephys): current clamp with no injected current, so current clamp technique / electrophysiological approach, the same as CurrentClampSeries. Before this, a file whose only intracellular data was IZeroClampSeries got no icephys metadata.
• RoiResponseSeries (ophys): no technique, since ROI traces can come from one- or two-photon imaging, and microscopy approach; cell population imaging, matching ImagingPlane and PlaneSegmentation.
• OptogeneticStimulusSite: the key and neurodata_type were spelled OptogeneticStimulusSIte, so the entry never matched the real type. The existing test case used the same typo, so I fixed it there too.

Added test_ndtypes cases for the two new types. dandi/tests/test_metadata.py passes locally, and so do the pre-commit hooks.

Context: dandi/dandi-archive#2907 / dandi/dandi-archive#2946, which make archive search match NWB subtypes and rely on this map. The bigger gap, extension types that subclass a core type (e.g. an ElectricalSeries subclass), is also dropped here. Fixing that means resolving unknown types through the schemas cached in the file, which I'll leave for a separate change (see the TODO in get_neurodata_types_to_modalities_map).

Suggested change

	"technique": None,
	"technique": "surgical technique",

I wonder if we should include this here, or just keep as is to the typo fix?

could go in without further refine per comment to not make perfect be enemy of the good.

Just FTR: would cause conflicts with
