This is a clone of issue OCPBUGS-5547. The following is the description of the original issue:

Description of problem:
This is a follow-up on https://bugzilla.redhat.com/show_bug.cgi?id=2083087 and https://github.com/openshift/console/pull/12390

When creating a Knative Service and delete it again with enabled option "Delete other resources created by console" (only available on 4.13+ with the PR above) the secret "$name-github-webhook-secret" is not deleted.

When the user tries to create the same Knative Service again this fails with an error:

An error occurred
secrets "nodeinfo-github-webhook-secret" already exists

Version-Release number of selected component (if applicable):
4.13

(we might want to backport this together with https://github.com/openshift/console/pull/12390 and OCPBUGS-5548)

How reproducible:
Always

Steps to Reproduce:

1. Install OpenShift Serverless operator (tested with 1.26.0)
2. Create a new project
3. Navigate to Add > Import from git and create an application
4. In the topology select the Knative Service > "Delete Service" (not Delete App)

Actual results:
Deleted resources:

1. Knative Service (tries it twice!) $name
2. ImageStream $name
3. BuildConfig $name
4. Secret $name-generic-webhook-secret

Expected results:
Should also remove this resource

1. Delete Knative Service should be called just once
2. Secret $name-github-webhook-secret

Additional info:
When delete the whole application all the resources are deleted correctly (and just once)!

1. Knative Service (just once!) $name
2. ImageStream $name
3. BuildConfig $name
4. Secret $name-generic-webhook-secret
5. Secret $name-github-webhook-secret
