Fix manim rendering when the code block starts with python (#42)

* Update dependencies

aiohttp (3.8.1) was not supporting PEP 517 builds. (on M1)

* Fix manim rendering when the code block starts with `python`

regex union matches are eager so when it found `py` it stopped, without looking for `python`

* More detailed instructions in the README
