Inexistent function reference in pvlib.irradiance.poa_components

[echedey-ls]

The following referenced function does not exist:

pvlib-python/pvlib/irradiance.py

Line 474 in 19c9598

as calculated by an albedo model (eg. :func:`grounddiffuse`)

A alternative should be found and referenced with :py:func`pvlib.<submodule>.<function_name>`

[cwhanse]

Should point to :py:funcpvlib.irradiance.get_ground_diffuse

Good first issue for newcomers or do you prefer a PR?

I like the idea of leaving it, so we have something in case someone comes by.
