Align examples/python/testapp/init.sh token names to README

[DMaillouxPANW]

Description

The provided example commands at the end of examples/python/testapp/init.sh call the tokens mtok and jtok.

This conflicts with the naming convention in examples/python/testapp/README.md.

Motivation and Context

This change renames them TOKEN_M and TOKEN_J to make this more consistent and help avoid confusion.

How Has This Been Tested?

This is a non-breaking change and therefore is untested.
