API-24392: Remove test feature from VBADocuments enabled_features config

[kristen-brown]

Summary

The VBADocuments::FlipperStatusAlert job alerts Slack when VBADocuments (Benefits Intake) features that are expected to be enabled are not enabled. A "test" feature flag had previously been added to the config for enabled features to check, to ensure that the feature was working as expected (since there are no active feature flags for VBADocuments currently). The alerting feature has been verified as working as expected, so this PR removes the "test" feature flag from the config.

When I removed the last remaining feature from enabled_features.yml, the "no features found" Slack alert kicked in before the BulkFeatureChecker could be called, leading to test failures.
