markdown-it-py, mdit-py-plugins: allow disabling the test suite

the test suite pulls in a huge number of dependencies, from cryptography
over sphinx to zope. since we want to use markdown-it-py in the nixos
manual build and closure size is important we'll skip the test suite for
the manual and rely on the regular builds to catch test failures. it's
not ideal, but markdown-it-py is the closes thing to the official MyST
parser we can get right now.
