Conditionally render SourceLinks based on view context

Feature Description

---

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

Acceptance criteria

• Any widgets that include one or more SourceLinks should be adjusted to only render these source links if not in the view-only version of the dashboard. The useViewOnly() hook introduced in Use alternate viewContext for non-authenticated users #4814 should be used to determine that.
  • The reasoning behind this change is that the links go to the Google frontend to which you'll only have access if authorized within Google's permission system. The view-only users won't have access to this in the vast majority of cases, therefore these links should not be shown.

Implementation Brief

• In assets/js/components/SourceLink.js:
  • Call the useViewOnly() hook introduced in Use alternate viewContext for non-authenticated users #4814. If it is false, return null.

Test Coverage

• No new tests to be added.

QA Brief

• All source links at the bottom of widgets should continue to appear as normal for a user not using Dashboard sharing.

Note for future QA

• This will not be possible to QA now, but in the future when a user can browse the dashboard using Dashboard sharing in a "view-only" mode, the "Source: {Service}" links at the bottom of widgets should not appear when browsing in a read-only mode.

Changelog entry

• Update source links to hide on the view only dashboard.
