Match the house wording for the Python prerequisite

Lab D stated a 3.10-3.13 range because the [redteam] extra pulls PyRIT,
which has no 3.14 build. That is true, but 3.13 already sits inside the
supported range, so the extra precision only made this lab read differently
from the others.

Now matches A, B and C. The 'tested with 3.13.12' sentence is left off,
since nothing in this lab has been run yet.
