This pull request is necessary to ensure that Python versions beginning with 3.10 are available as default shell options on the Guake terminal. Without this modification the newest Python version that would function on the Guake terminal is only Python 3.9, and Ubuntu 22.04 LTS (my host system) ships with Python 3.10 by default, causing the issue of Python 3.10 not appearing on my host system.

By changing the regex for the Python interpreter listings, versions of the Python 3.x interpreter newer than late-2021 should be permitted as options for the Guake drop-down terminal. The command for "python3.10" as well as commands for newer versions of Python 3 violate the rules created by the old regex (from the first commit). This second commit should enable the "ipython3" and legacy "ipython2" commands on Linux distributions that differentiate between Python 2 and Python 3 versions of the IPython interpreter.
