[24/27] configure: Add courtesy hint to Python version failure message

Commit Message

If we begin requiring Python 3.7+, a few platforms are going to need to
install an additional Python interpreter package.

As a courtesy to the user, suggest the optional package they might need
to install. This will hopefully minimize any downtime caused by the
change in Python dependency.
