Add invite email experiment

See merge request gitlab-org/gitlab!39628

This creates an experiment for a new invite email design that is

Complete CRUD for group-level integrations

See merge request gitlab-org/gitlab!39959

After adding the CRUD for group-level integrations
https://gitlab.com/gitlab-org/gitlab/-/merge_requests/27557, we were
missing the group_id column
https://gitlab.com/gitlab-org/gitlab/-/merge_requests/38499, so an
integration cannot belong to a group.

This completes the work, having now group-level integrations.
