velero: upgrade to 1.17.1 (chart 11.4.0)

1.17 drops restic, which nothing here uses (all 411 pod volume backups and 20 repositories are kopia), and moves the maintenance job settings from server flags into the velero-repo-maintenance ConfigMap, which the chart now renders with keepLatestMaintenanceJobs: 3. The AWS plugin goes to v1.13.2, the line for Velero 1.17.
