[BUG] Invalid /metadata/name format for generated ids of Integration

[igarashitm]

Describe the bug
The auto-generated /metadata/name uses upper case character which is not allowed

[tomo@p1 camel-k]$ kubectl apply -f example.integration.yaml
The Integration "Integration1687900965845" is invalid: metadata.name: Invalid value: "Integration1687900965845": 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?)*')

To Reproduce
Steps to reproduce the behavior:

1. Choose Integration or Kamelet
2. deploy generated YAML onto k8s

Expected behavior
Use lowercase
