Migrate `g_edit_by_sfe` correctly to internal events

Problem

While investigating metrics that should be moved to InternalEvents we found that g_edit_by_sfe has not been correctly converted yet. The call in https://gitlab.com/gitlab-org/gitlab/-/blob/master/app/controllers/projects/blob_controller.rb#L41 will need to be updated to InternalEvents.

Desired Outcome

g_edit_by_sfe is correctly updated to Internal Events.

Possible Solution

• Migrate the call in https://gitlab.com/gitlab-org/gitlab/-/blob/master/app/controllers/projects/blob_controller.rb#L41
• The event_name in this case should be changed to g_edit_by_sfe since this is the canonical name for this event also within redis.
• The data_source for aggregated metrics including g_edit_by_sfe should also be updated accordingly if all other events included in the metric are already converted.
