Remove unmatched '`' from README.rst

This may seem extremely minor, but I'd (jokingly) argue it falls under UX, since I was confused and thought I had dirt on my screen screen due to this lone '`'.
It cost me a whole 5s, then another 5m to write this PR, but if it confuses at least 60 people a day then maybe its worth it?
Anyways, enjoy this extremely minor change that will hopefully eliminate a still really minor annoyance.
