monkey patch rtd theme CSS glitch

This should hopefully prevent horizontal stacking of short items in the html documentation.

@FoamyGuy, this is for adafruit/Adafruit_CircuitPython_FruitJam#17 (comment), as requested.

I haven't tested whether this actually works. Merge with caution.

This page describes the process that would be used for testing it out if you want to give it a try: https://learn.adafruit.com/creating-and-sharing-a-circuitpython-library/creating-a-library

After creating a library with that process then can put some of the offending code from Fruit Jam or TLV that have the properties stacking problem into it and build the docs inside of it.

I'll test it out in the next few days / next week if you don't get to it or would rather not work through that process.

Cookiecutter isn't really my thing. It's been so long since I touched it, I don't remember how it works. I also have no clue about how it's integrated with Adafruit's backend systems. I might not be the best person to test this.

[edit: also, I'm neck deep in debugging usb.core.Device stuff]

This would be good to have still. Sorry I lost track of it. I will bring it back in a new PR

[samblenny]

oh, sorry! I think I zapped this PR accidentally when I was cleaning up forks that I couldn't remember why I'd even made.
