[Feature flag] group_coverage_data_report_graph - Enable group coverage report overall activity

What

Remove the :group_coverage_data_report_graph feature flag ...

Owners

• Team: Testing
• Most appropriate slack channel to reach out to: #g_testing
• Best individual to reach out to: @shampton, @morefice, @jheimbuck_gl, @mfluharty

Expectations

What are we expecting to happen?

Should show a section on the group repositories analytics page to show the latest code coverage activity data for the group.

Should also enable a GraphQL API for codeCoverageActivities in a group.

What might happen if this goes wrong?

The section does not work properly, or the GraphQL API doesn't work as expected.

What can we monitor to detect problems with this?

If we can monitor the API for response times that should be sufficient (or load time on the page even better).
