fix(backend/kubernetes): Ensure valid naming of name field (#1661)
- Kubernetes v1.26 on VKE causes error when creating persistent volume
claim because of uppercase characters in name field

This patch is trivial just in order to get it working - happy to
implement differently.

The error in question:

```
The PersistentVolumeClaim "wp-01G1131R63FWBSPMA4ZAZTKLE-0-clone-0" is invalid: metadata.name: Invalid value: "wp-01G1131R63FWBSPMA4ZAZTKLE-0-clone-0": a lowercase RFC 1123 subdomain must consist of lower case alphanumeric characters, '-' or '.', and must start and end with an alphanumeric character (e.g. 'example.com', regex used for validation is '[a-z0-9]([-a-z0-9]*[a-z0-9])?(\.[a-z0-9]([-a-z0-9]*[a-z0-9])?)*')
```
