prereq.sh fails to install python3-pip on clean Rocky9.3

[nthorne-dell]

Describe the bug
prereq.sh uses python's pip module to install ansible. If running it on Rocky Linux version 9.3 (Dell reasons why that version is picked)

To Reproduce
Steps to reproduce the behavior:

1. Request PXE image from internal network - should be a reasonably vanilla Rocky9.3
2. git clone https://github.com/dell/omnia.git
3. ensure correct permissions on directories
4. run prereq.sh
5. See error
   [root@controlplane omnia]# ./prereq.sh
   #[SNIP]

---

UPGRADING PIP:

/usr/bin/python3.9: No module named pip

INSTALLING ANSIBLE:

/usr/bin/python3.9: No module named pip
/usr/bin/python3.9: No module named pip
Waiting for process with pid 11608 to finish.

Or script halts on error
