Jeff McCune 78cec76a96 (#48) Restore ZITADEL from point in time full backup
A full backup was taken using:

```
kubectl annotate postgrescluster zitadel postgres-operator.crunchydata.com/pgbackrest-backup="$(date)"
```

And completed with:

```
❯ k logs -f zitadel-backup-5r6v-v5jnm
time="2024-03-10T21:52:15Z" level=info msg="crunchy-pgbackrest starts"
time="2024-03-10T21:52:15Z" level=info msg="debug flag set to false"
time="2024-03-10T21:52:15Z" level=info msg="backrest backup command requested"
time="2024-03-10T21:52:15Z" level=info msg="command to execute is [pgbackrest backup --stanza=db --repo=2 --type=full]"
time="2024-03-10T21:55:18Z" level=info msg="crunchy-pgbackrest ends"
```

This patch verifies the point in time backup is robust in the face of
the following operations:

1. pg cluster zitadel was deleted (whole namespace emptied)
2. pg cluster zitadel was re-created _without_ a `dataSource`
3. pgo initailized a new database and backed up the blank database to
   S3.
4. pg cluster zitadel was deleted again.
5. pg cluster zitadel was re-created with `dataSource` `options: ["--type=time", "--target=\"2024-03-10 21:56:00+00\""]` (Just after the full backup completed)
6. Restore completed successfully.
7. Applied the holos zitadel component.
8. Zitadel came up successfully and user login worked as expected.
