fix dra-driver version in alm-example

[rahulait]

Description

The GPUCluster alm-example in the OLM bundle referenced an outdated DRA driver version. This PR removes the explicit image reference so the operator uses the default DRA driver image configured through DRA_DRIVER_IMAGE.

📝 Walkthrough

Walkthrough

The GPUCluster sample now uses the nvcr.io/nvidia repository and version v0.5.0 for its DRA driver image. The CSV GPUCluster example removes the DRA driver image settings and retains computeDomains. The CSV update script no longer updates DRA driver fields for GPUCluster examples. It continues to update NVIDIADriver examples.

Merge Risk: ⚪ Minimal · up to a3aa5

The packaged example uses the configured DRA driver image when its fields are omitted. No actionable merge risk is evident.
