Update bundle status with error when encountering problem with sources files

[Shawcs]

Hi !

I noticed that the status do not reflect problem with bad/empty sources.

---

How to reproduce:

create a bundle that target a ConfigMap with a valid cert entry

apiVersion: trust.cert-manager.io/v1alpha1
kind: Bundle
metadata:
  name: my-bundle
spec:
  sources:
    - configMap:
        key: ca.crt
        selector:
          matchLabels:
            trust-bundle.my-bundle: include
  target:
    additionalFormats:
      pkcs12:
        key: ca.p12
        password: changeit
    namespaceSelector:
      matchLabels:
        kubernetes.io/metadata.name: infra
    secret:
      key: ca.crt

kind: ConfigMap
apiVersion: v1
metadata:
  name: my-cert.crt
  namespace: infra-cert-manager
  labels:
    trust-bundle.my-bundle: include
data:
  ca.crt: |

    -----END CERTIFICATE-----

the bundle status should change to :

  conditions:
    - lastTransitionTime: '2024-09-10T13:24:17Z'
      message: 'Successfully synced Bundle to namespaces that match this label selector: kubernetes.io/metadata.name=infra'
      observedGeneration: 1
      reason: Synced
      status: 'True'
      type: Synced

go to the source cert in the configMap and "destroy" it by adding some characters inside the cert

kind: ConfigMap
apiVersion: v1
metadata:
  name: my-cert.crt
  namespace: infra-cert-manager
  labels:
    trust-bundle.my-bundle: include
data:

    G3VnreyXrukwRbMI/MR4ccXl5/n+Hw==
    -----END CERTIFICATE-----

the status is still the same in the bundle (and is not re generated in destination namespace), but in the operator we can read:

Suggestion

I suggest that when we have this kind of error the status in the bundle is updated with a relevant error. This also work for the case where source is empty
