grafana-backup-tool doesn't restore alert rules from backup (although files with alert_rules exist in backup archive)

[rustjalm]

We use:
Grafana 9.4.3
grafana-backup-tool 1.3.1docker version)

grafana-backup-tool doesn't restore alert rules. Other parts (dashboards, users, datasources etc. restore successfully). When restore we have error 404 'could not find alert rule':

But files with alert_rules backups exist in archive:

[rustjalm]

Problem resolved by upgrade Grafana from 9.4.3 to 9.5.3
