build: remove html_insert_assets complication from integration/bazel (#34112)

For the purposes of the integration test the zone.js script & bundle script tags could just go into the source index.html itself. The purpose of the integration test is is to test @angular/bazel & ng_module & ng_package so there is no need to exercise html_insert_assets.
