ci: disable redundant Angular bot size check

The E2E test suite contains a production build test (`build/prod-build`) that performs
a size comparison check to ensure a production build of a newly generated application
stays within 10% of a predefined value (currently 124,000 bytes).
As a result of this preexisting check, the need to perform another check that involves
the added complexity of Github status hooks and API calls is currently not needed.
