fix(scripts): make get-yatai-system-kubeconfig.sh compatible with kubernetes 1.24+

The LegacyServiceAccountTokenNoAutoGeneration feature gate is beta, and enabled by default. When enabled, Secret API objects containing service account tokens are no longer auto-generated for every ServiceAccount. Use the TokenRequest API to acquire service account tokens, or if a non-expiring token is required, create a Secret API object for the token controller to populate with a service account token by following this guide.
