gh-143993: Document ways to disable remote debugging support (GH-143994)

Although PEP 768 mentions how to disable the mechanism of
remote debugging, it is not documented in the Python docs.

This change adds a note on how to disable remote debugging support
in a Python interpreter to the remote debugging how-to.
(cherry picked from commit 0b5f8359c52f8a5ce0fe436cde499553f3b8f5d5)
