Subject: [PATCH] Fixed mistake in Python enum for not correcting refraction.

GitHub user `hidp123` submitted the following pull request:
https://github.com/cosinekitty/astronomy/pull/240

The problem was I had documentation for the Python enum
`Refraction` where I incorrectly wrote `Refraction.None`
instead of the correct name `Refraction.Airless`.

The fix in the pull request was correct, but it was
applied to generated source code, so it did not correctly
update the template file or the online documentation.

This commit fixes the mistake in all the affected files.
