Update cyberpanel.sh - fix python3-packaging problem with pip

Added code prior to the script's python virtualenv install that upgrades python's 'packaging' package. Recent changes by the pypi team to pip will cause an error of "strip-trailing-zero" in versions of "packaging" that are lower than 22.
- code executes pip command to install/reinstall the "packaging" package, even if the package was installed by your distro package manager. 
*** AlmaLinux 9 (and likely other yum/dnf distros) uses version 20.9 of "packaging" in the rpm repos. Other distros may be affected. ***
