fix: use multi-arch digest for kubevirt-dp instead of amd64 digest

[cdesiniotis]

Starting with v1.5.0 of the NVIDIA KubeVirt GPU Device Plugin, images that get published to nvcr.io are multi-arch. The image digest in the OLM bundle is incorrectly referring to the amd64 digest, causing the following error when this image is launched on an ARM server:

exec container process `/usr/bin/shelless_ulimit`: Exec format error

This commit updates the digest to refer to the multi-arch digest.
