misc/py-numcodecs: Fix RUN_DEPENDS

• Change from py-numpy to py-numpy
• Do not bump PORTREVISION because this port does not build before

bbea9171d95c59cc03d10c677a166373137d5208 breaks all dependent ports.
For example:

• devel/py-anndata
• devel/py-xarray
• devel/py-xarray-simlab
• devel/py-zarr
• filesystems/py-kerchunk
• graphics/py-imagecodecs
• graphics/py-imageio
• graphics/py-scikit-image
• graphics/py-tifffile
• math/py-mathics
• misc/py-napari
• www/py-sentinelhub
