Enable SAST in Auto DevOps template

Because of an urgent fix for Code Quality in the Auto DevOps templates, a new version of the template has been created. The fix is intended to go in %10.2 and we don't want SAST to run until it is officially released in %10.3.

Unfortunately the vendoring process doesn't allow a different process, the already merged sast job definition will be removed (gitlab-ci-yml!117 (merged)).

As soon as the patch will be released for %10.2, we need to add again sast job definition to the template, so it can be picked up in %10.3 as expected.
