SERVER-94731 introduced additional change stream events for `system.views` in master. Assertions that these events should occur were added to jstests/change_streams/ddl_view_event.js as part of that change.

These additional change stream events are not present in v8.0, so multiversion-testing that file would have caused issues. However, multiversion tests for jstests/change_streams/ddl_view_events.js were blacklisted in etc/backports_required_for_multiversion_tests.yml by a previous change (SERVER-88142).

The issue became a problem yesterday when the backport of SERVER-88142 was merged into v8.0, which re-enabled the multiversion tests for jstests/change_streams/ddl_view_event.js.

To fix the issue, we need to adjust the checks for system view creations in jstests/change_streams/ddl_view_event.js so that they only run when the mongod version is >= 8.1.
