How Has This Been Tested?

No testing needed

Test Impact

No test impact

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 or cypress tests 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).

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

@andrewballantyne @VaishnaviHire @zdtsw Please take a look at this, we missed the removal of this github action when we refactored the manifest deployment into the dashboard repo. Let us know if this is still used anywhere, if not, we can approve and merge this PR.

Thanks a lot.
