MR License Compliance Widget not showing on staging as old widget unavailable

As per failure on Staging noted in #372959 (closed)

It was noticed that License Compliance widget was no longer appearing on Merge Requests.

The old vue has been removed, refactor_mr_widgets_extensions FF was turned off.

Hey team, ran into a weird edge case with feature flags. I think license compliance is the first widget to have the old design removed in this MR. But this also means if we ever turn off :refactor_mr_widgets_extensions then we won't show any license compliance widgets, since the old vue doesn't exist anymore

Analysis

:refactor_mr_widgets_extensions flag was off in staging, but enabled in production and self-managed via the YML file.

I turned on the flag in staging so the new widget is visible in staging https://staging.gitlab.com/secure-team-test/security-reports/-/merge_requests/28

Options

Decouple flag

WIP MR !97536 (merged) to see if we can enable decouple the widget from the :refactor_mr_widgets_extensions
