[BUG] ./scripts/devenv-builder/configure-vm.sh: nothing provides openshift-clients needed by microshift

[IceCodeNew]

What happened?

I was following the steps of docs/devenv_setup.md to set up a development environment.
The script configure-vm.sh failed with the following error:

Error: 
 Problem: conflicting requests
  - nothing provides openshift-clients needed by microshift-4.14.0_0.nightly_2023_06_20_065807_20230626095221_42021b5d6-1.el9.x86_64 from @commandline
(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)

What did you expect to happen?

The script configure-vm.sh should be able to install the openshift clients without depending on the repositories of RHEL.

How to reproduce it (as minimally and precisely as possible)?

1. Create a brand new VM with the latest CentOS 9 Stream ISO
2. Clone this repo under the home dir of user microshift
3. ssh microshift@${VMIPADDR} "~/configure-vm.sh ~/.pull-secret.json"

Environment

• MicroShift version (use microshift version): has nothing to do here
• Hardware configuration: AMD64, 4C8G, 200GB storage
• OS (e.g: cat /etc/os-release):

PLATFORM_ID="platform:el9"
PRETTY_NAME="CentOS Stream 9"

The openshift-client RPM dependency was added in #1376 and it broke the installation on CentOS.

[ggiguash]

On CentOS, we could download and install openshift-clients RPM from the mirror repository.

For example:

curl -s https://mirror.openshift.com/pub/openshift-v4/dependencies/rpms/4.14-el9-beta/ | grep -o "openshift-clients-4[^\"']*.rpm" | sort | uniq
openshift-clients-4.14.0-202306270854.p0.gc078876.assembly.stream.el9.x86_64.rpm

@IceCodeNew , would you like to test the script I uploaded in the #1976 PR?
