numpy intersphinx object inventory changed

[mikofski]

Describe the bug
the new url is https://numpy.org/doc/stable/

To Reproduce
Steps to reproduce the behavior:

pvlib-python/docs/sphinx/source/conf.py

Line 319 in b0d29f5

'numpy': ('https://docs.scipy.org/doc/numpy/', None),

this goes to the main scipy docs page, not NumPy

Expected behavior
where ever numpy functions, classes, etc are used, they should be automatically linked, but they are not

Screenshots
I didn't look for one

Versions:

• 0.8.1

Additional context
I wonder if we really even need this, and we don't have an intersphinx mapping for scipy

Relevant log output from the most recent latest RTD build:

intersphinx inventory has moved: https://docs.scipy.org/doc/numpy/objects.inv -> https://numpy.org/doc/stable/objects.inv

I wonder if we really even need this, and we don't have an intersphinx mapping for scipy

I think the intersphinx links are nice to have and and worth keeping as long as they aren't much effort to maintain. Especially in the example gallery I imagine it is convenient for some users to have wikipedia-style cross-links as they read ("what does np.unique do again?")
