fix title of Pr automation updater for kubernetes version

[medyagh]

this is the title I saw here #21223 (fixed it manually)
cd hack && go run update/kubernetes_version/kubernetes_version.go Bump Kubernetes version default: v1.33.3 and latest: v1.34.0-beta.0

it should be

Bump Kubernetes version default: v1.33.3 and latest: v1.34.0-beta.0

source of issue probably is we need to bring back @ in https://github.com/kubernetes/minikube/blob/95d4cfe1a0eb90be21a250711906174689b0b4aa/Makefile#L1069C3-L1069C68
