third_party/Python-Markdown: Update to 3.3.4

Update Python-Markdown to 3.3.4. Version 3.3.5+ requires
importlib-metadata>=4.4, which requires Python 3.7+ according to
Gentoo's ebuild file. However, the current Python version in chromium
chroot is 3.6, so that's infeasible.

Update README.chromium.
