Which issue this PR addresses:

With PR: #2450 merged, I have added cluster installation failed in the error message and step hiveClusterDeploymentReady will also be run during the Update path, the existing error message will confuse customers.

This PR modifies the error message by removing the install word in the error.

I'll be honest, I'm not intuitively seeing how this wording improves the customer experience. These are customer errors, right? If I'm a customer, I don't care about "conditions" or "hive", etc, what I care about is that I couldn't create a cluster, and ideally, why that happened... These timeouts would be sometimes my problem (e.g. a policy in my sub blocked the deployment, and Tanmay and Swetha are working on changing that), but sometimes our problem as SREs. I'm not sure this new message clarifies any of that to me, from a customer perspective, and actually removes useful information in the message (that the cluster installation has failed).

LGTM

LGTM but I don't think we need to rush, cut a new release and re-run INT to include this change.

IMO it could wait for next release

@rogbas I greee, it is LGTM, it makes sense to me, but it can wait.

Not sure the error messages are actually all actionable. Might be a good idea to discuss this with the PMs for a next iteration.
