test: add setting to ignore version compatibility toast warnings in e2e tests (#7004)

There's a warning toast shown if the frontend is considered out-of-date
(relative to the version in the requirements.txt of
comfyanonymous/ComfyUI). As a result, e2e tests run on older release
branches (e.g., when backporting or hotfixing) can sometimes trigger the
warning which obviously causes visual regression tests to fail. This PR
adds a hidden setting to disable the warning and sets it to `true` in
the e2e test fixtures.
