[BUG][Minor] get-uls.sh requires pip 22.2

[bitonio]

On a fresh Rocky 9, the get-uls.sh script spills out some pip error due to the argument --dry-run introduced at version 22.2.

# pip3 --version
pip 21.2.3 from /usr/lib/python3.9/site-packages/pip (python 3.9)

To simple solve the issue, upgrade pip with pip install --upgrade pip. There might be other option with the dnf package manager.

I made some change to detect pip version and that should offer a better experience on old systems:

[root@172-XXX-XXX-XX ~]# bash get-uls.sh

pip3 version must be >= 22.2, version detected: 21.2.3
Consider upgrading your PIP version with command:
  /usr/bin/pip3 install --upgrade pip
