Remove Berries Workflow Flag

[fergmac]

Describe the task
The Berries workflow introduced a feature flag to turn the feature on and off. Now that the berries workflow has been validated in production the feature should be on for all users.

Purpose
When a feature flag is created it's a good practice to create a task to remove the flag in the future. If flag's are not cleaned up they can create confusion especially as more flags are added.

Acceptance Criteria

• The Berry workflow is on for all users.
• References to the feature flag is removed from the code.
• Feature flag is removed from related OpenShift environment.

Additional context

• The appsettings.json file contains a FLAG_BERRIES_WORKFLOW flag that can be turned off/on.
