Fix build breakage from prism-go-client v0.5.5 → v0.7.1 upgrade

[Copilot]

Summary

PR #167 (Dependabot bump of prism-go-client v0.5.5 → v0.7.1 and logrus v1.9.3 → v1.9.4) was blocked because prism-go-client v0.6.0 changed ClusterSpec.Name and ClusterStatus.Name from *string to string. The driver code was still dereferencing these as pointers, causing compilation failures:

machine/driver/driver.go:178:7: invalid operation: cannot indirect peSpec.Name (variable of type string)
machine/driver/driver.go:189:47: invalid operation: cannot indirect foundClusters[0].Status.Name (variable of type string)

Changes

• go.mod / go.sum: Bump prism-go-client v0.5.5 → v0.7.1, logrus v1.9.3 → v1.9.4, and associated transitive dependency updates (go-logr/logr, google/go-cmp, protobuf, stretchr/testify, k8s.io/utils)
• machine/driver/driver.go: Remove invalid pointer dereferences on now-value-typed Name fields

// Before
if *peSpec.Name == d.Cluster { ... }
log.Infof("Cluster %s found with UUID: %s", *foundClusters[0].Status.Name, ...)

// After
if peSpec.Name == d.Cluster { ... }
log.Infof("Cluster %s found with UUID: %s", foundClusters[0].Status.Name, ...)

Fixes the CI failures reported in #167.
