gnu: python-numpy: Alias to python-numpy-1.20.

Numpy 1.20 is required by numba and umap-learn.  Attempts to rename numpy 1.20
to allow it to coexist with numpy 1.21 in the same environment have not been
successful.

* gnu/packages/python-xyz.scm (python-numpy): Rename to...
(python-numpy-next): ...this variable.
(python2-numpy): Use python-numpy-next package as parent.
(python-numpy-1.20): Inherit from python-numpy-next.
(python-numpy): New variable pointing to python-numpy-1.20.
(python-numba)[propagated-inputs]: Replace python-numpy-1.20 with
python-numpy.
