[Feature]: [OpenShift] Remove `${RHEL_VERSION}` from amdgpu-driver container tag

[LaVLaS]

Suggestion Description

OCP support for building the amdgpu driver from the amdgpu-driver container image relies on an imageTag containing the OS Version & driver version like coreos-9.6-30.20.1. This reduces the range of OCP versions that can build and install drivers using the source container image.

Related to #550

Unless the OS Version is being intentionally kept in the imageTag name to restrict the OCP versions, it should be dropped to rely solely on {OS NAME}-{DRIVER_VERSION}. This would maintain flexibility for distro support OCP vs xKS while allowing users to match the driver version based on their environment needs.

Additionally, I did some quick comparisons and the source code provided by amdgpu-dkms packages for the .rpm, .deb and container image appear to have matching filehashes with the only difference being distro specific customizations for dkms and packaging requirements. Potentially the source images could be the raw amdgpu-dkms source files without the .deb or .rpm files included
