ci(workflows): remove pkg-size-report

- https://github.com/pkg-size/action/blob/v1.1.1/src/lib/build-ref.js#L97
- https://github.com/flex-development/mlly/actions/runs/4340518862/jobs/7579134604
- action does not work; thinking `git reset --hard` should not be called given current options
