Remove userFeedback feature flag

Since the feature is fully rolled out, we should remove the userFeedback feature flag.

---

Do not alter or remove anything below. The following sections will be managed by moderators only.

Acceptance criteria

• The userFeedback feature flag should be removed
• All code that has been activated when the userFeedback feature flag is enabled should work unconditionally now.
• All code that has been deactivated when the userFeedback feature flag is enabled should be removed.

Implementation Brief

• Update feature-flags.json to remove userFeedback
• Search for the userFeedback string within the code base and review code where the userFeedback is present. Any logic/component which was rendered conditionally when the userFeedback feature was enabled should be rendered unconditionally now. Any code which was rendered when the feature flag was disabled should be removed.
• Use of the useFeature hook with userFeedback as a parameter should be removed.

Test Coverage

• No new tests to be added

Thanks for the PR @Patil2099! Normally it’s difficult for us to accept PRs from the community but in this case the changes are so small and ready to go that we should be able to use it 👍
