bug#55027: 28.1; User option python-forward-sexp-function in wrong group

[Howard Melman]

The defcustom for python-forward-sexp-function in python.el is in the
python-flymake defgroup. I believe it should be in the python defgroup.

It should probably be moved to the ;;; Navigation section of the file,
but certainly before the defgroup for python-flymake
