[backport v2.13] Certain errors not being shown in gitjob conditions

[rancherbot]

This is a backport issue for #3973, automatically created via GitHub Actions workflow initiated by @0xavi0

Original issue body:

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

Discovered while testing #3880

A not found helm secret name is not displayed in the UI, but they are found in the events of the gitrepo. It seems certain errors are not shown on gitjob conditions.

Expected Behavior

The UI should reflect this error because we can correctly process it.

Steps To Reproduce

Follow as reference steps defined in the reference ticket.

I managed to reproduce like this:

• Prepare Rancher cluster, zot and Docker registry as explained in referenced ticket: [backport v2.11] insecure-registries no longer respected in fleet-cli #3880 (comment)
• Create secret:
  kubectl create secret -n fleet-local generic oci-helm-secret --from-literal=basicHTTP=false
• Deploy gitrepo. I used:

apiVersion: fleet.cattle.io/v1alpha1
kind: GitRepo
metadata:
  name: sample
  namespace: fleet-local
spec:
  repo: "https://github.com/mmartin24/test-fleet/"
  branch: master
  paths:
  - "3888-docker"
  helmSecretName: oci-helm-secret

• Observe how the repo cannot be deployed an an error appears (expected)
• Delete the secret
• Force update
• Observe the UI does not display anything but in the gitrepo events we show the reason: failed to look up helmSecretName, error: Secret "oci-helm-secret" not found
