Angstrom symbol does not render in Sphinx docs

[sean-lockwood]

Getting "\AA" instead of "Å".

For instance:
https://pysynphot.readthedocs.io/en/latest/units.html#constants

Probably related: mathjax/MathJax#795

My solution to this was to add the following rst_prolog in conf.py:

rst_prolog = u"""\

.. only:: html

  :math:`\renewcommand\AA{\text{Å}}`
