Remove rubocop CodeReuse/ServiceClass

This comment was added because previously the `Integrations::Jira` model
was named `PrometheusService` which triggered the cop.

The model was renamed in
https://gitlab.com/gitlab-org/gitlab/-/merge_requests/61743 however it
was missed that we could remove this pragma comment until
https://gitlab.com/gitlab-org/gitlab/-/merge_requests/62645#note_602285858
