tar package is missing in pgbackrest image

Proposal

Hi Team,
I want to copy out the backups stored in repo-host to have it externally, but it seems that tar package is not included in percona-pgbackrest:2.58.0-2 image.

kubectl cp db-cluster-repo-host-0:/pgbackrest/repo1/test1 .test
error: Internal error occurred: Internal error occurred: error executing command in container: failed to exec in container: failed to start exec "3cd4c482e3f4809dde7d18b20520012208921684d9b8aa1ae4155c76a8b784e9": OCI runtime exec failed: exec failed: unable to start container process: exec: "tar": executable file not found in $PATH: unknown

kubectl exec -it db-cluster-repo-host-0 -c pgbackrest -- /bin/bash
bash-5.1$ tar
bash: tar: command not found

Best regards,
Grzegorz

Use-Case

Possibility to store backups externally, in case we not able to use s3 bucket or others.

Is this a feature you are interested in implementing yourself?

No

Anything else?

No response

Start by inspecting how the percona-pgbackrest:2.58.0-2 image is built and reproduce the kubectl cp failure shown in the issue. Done means the image includes tar and kubectl cp can copy backup contents from the repo-host container for the stated use case.
