updated test to reflect Unknown to unknown

Request review criteria:

Self checklist (all need to be checked):

• The developer has manually tested the changes and verified that the changes work
• Commits have been squashed into descriptive, self-contained units of work (e.g. 'WIP' and 'Implements feedback' style messages have been removed)
• Testing instructions have been added in the PR body (for PRs involving changes that are not immediately obvious).
• The developer has added tests or explained why testing cannot be added (unit tests & storybook for related changes)

If you have UI changes:

• Included any necessary screenshots or gifs if it was a UI change.
• Included tags to the UX team if it was a UI/UX change (find relevant UX in the SMEs section).

@xianli123 This is just a fix from the past mocks

After the PR is posted & before it merges:

• The developer has tested their solution on a cluster by using the image produced by the PR to main

/override "Delete quay image on PR closed / delete-pr-quay-image (pull_request)"

[openshift-ci]

@andrewballantyne: /override requires failed status contexts, check run or a prowjob name to operate on.
The following unknown contexts/checkruns were given:

• Delete quay image on PR closed / delete-pr-quay-image (pull_request)

Only the following failed contexts/checkruns were expected:

• ci/prow/images
• ci/prow/odh-dashboard-pr-image-mirror
• delete-pr-quay-image
• pull-ci-opendatahub-io-odh-dashboard-incubation-images
• pull-ci-opendatahub-io-odh-dashboard-main-odh-dashboard-pr-image-mirror
• tide

If you are trying to override a checkrun that has a space in it, you must put a double quote on the context.
