[Backport v2.7-Patch1] etcd snapshot-restore with etcd v3.5.9 fails due to missing /bin/sh in etcd container image

etcd-restore image seems to be in failure loop additionally to the above issue.

There are no documented steps how to stop this loop and no documented workaround for rancher to manually restore etcd from snapshot created by rancher if the image is failing or rancher functionality is not working.

To Reproduce
perform restore etcd snapshot with gui on rancher 2.7.10

Result
etcd restore failure loop

Expected Result
etcd restore will try once or max 3 times, fail, informing user about failure.

it should be documented way to stop the etcd-restore job and restoring etcd manually.
