• The title of the PR is (a) conventional, (b) states what changed, and (c) suffixes the related issues number. E.g. "fix(controller): Updates such and such. Fixes #1234".
• I have written unit and/or e2e tests for my change. PRs without these are unlike to be merged.

I mistakenly modified the generated code in #2417 and the code has been overwritten in #2448
. I added the default namespace into workflow manifests because fake clients cannot handle an empty namespace correctly.

I also removed SkipNow added in #2433. Please just tell me if the tests are still flakey.
