[feature] Skip changelong not develop @W-17704536@ (#2257) (#2258)

* Skip the CHANGELOG check github action when not on `develop` branch @W-17704536@

* meaningless whitespace commit to trigger github actions CI

* Add auto-pass CI check behavior to satisfy other jobs with `depends-on: changelog-check`

* ensure changelog-check always runs

* add a whitespace change to the allow-listed PUBLIC_PACKAGES to validate PR check functionality https://github.com/SalesforceCommerceCloud/pwa-kit/blob/develop/.github/actions/changelog-check/action.yml#L58

* roll back demonstrative change
