MVC: Add Secret Detection to configuration page

Problem to solve

We are going to enable "Perform secret detection on full history". The status of Secret detection should be part of the "Configuration page" so that the user can manage all security scans in a consistent way.

Target audience

• Delaney, Development Team Lead
• Sasha, Software Developer
• Sidney, Systems Administrator

JTBD: When protecting my project, I want to the status of all scan types include secrets scans, so that I can be assured my project is well protected.

Implementation Plan

We need to work on following areas in order to add this feature on the configuration page:

• https://gitlab.com/gitlab-org/gitlab/-/blob/master/ee/app/controllers/projects/security/configuration_controller.rb#L11
• https://gitlab.com/gitlab-org/gitlab/-/blob/master/ee/app/presenters/projects/security/configuration_presenter.rb#L10
• https://gitlab.com/gitlab-org/gitlab/-/blob/master/ee/app/assets/javascripts/security_configuration/components/app.vue#L135

Proposal & Design

Add "Secret Scan" as part of configuration table
