Docs fail to build

[Witchblade101]

It looks like our docs have been failing their build for the last few months. The latest version on Read the Docs says "© Copyright 2021, STScI Revision 413bdcf."

Conda virtual environment I made to test this:
(Mostly for my own future reference)

`conda create -n pysiaf python=3.7
conda activate pysiaf
conda install sphinx
conda install numpy
conda install astropy
conda install numpydoc
conda install matplotlib
conda install lxml
conda install scipy
conda install openpyxl
conda install requests
conda install sphinx-automodapi
conda install pytest
pip install stsci-rtd-theme

git clone https://github.com/Witchblade101/pysiaf.git
cd pysiaf
pip install .
git remote add upstream https://github.com/spacetelescope/pysiaf.git
git checkout -b doc-update
`

Checked docs/conf.py dependencies:

`conda install ipython

ipython

import datetime
import importlib
import sys
import os
import stsci_rtd_theme
from distutils.version import LooseVersion
from ConfigParser import ConfigParser
ModuleNotFoundError: No module named 'ConfigParser'
from configparser import ConfigParser`

Looks OK.

Edited docs/pysiaf/index.rst:

"This package is being developed in a python 3.6 environment." ==> "This package is being developed in a python 3.7 environment."

"pysiaf is available on PyPI <https://pypi.org/project/pysiaf/>_ and is included in astroconda." ==> "pysiaf is available on PyPI <https://pypi.org/project/pysiaf/>_ "

Committed and pushed changes:

git add docs/pysiaf/index.rst commit -m "Updated python ver. and removed astroconda from docs" git push origin doc-update
