Steps to reproduce:

1. Download latest Template OS Linux by Zabbix Agent from release/5.4 or master branch (https://git.zabbix.com/projects/ZBX/repos/zabbix/browse/templates/os/linux/template_os_linux.yaml)
2. Try to import it to Zabbix 5.4 (via frontend)

Result:
Import failed

• Incorrect value for field "master_itemid": value "vfs.file.contents/sys/block/{#DEVNAME}/stat" not found.

See screenshot

I've tried to import same template from release/5.2 branch with same results.

Expected:
Template is imported, existing templates are updated.
