IndexError: list index out of range on Fedora release 37

ccm doesn't seems to be working on Fedora 37.

Installation steps:
pip install ccm

Defaulting to user installation because normal site-packages is not writeable
Requirement already satisfied: ccm in /home/workenv/.local/lib/python3.11/site-packages (3.1.5)
Requirement already satisfied: pyYaml in /usr/lib64/python3.11/site-packages (from ccm) (6.0)
Requirement already satisfied: six>=1.4.1 in /usr/lib/python3.11/site-packages (from ccm) (1.16.0)

Run test:
ccm create test -v 4.0.0 -n 3 -s

ccm create t-c1 -v 3.11.1 -n 3 -s

argparse 3.10 changed "optional arguments" to "options" (this commit). Changing the script locally worked.
