Disable minimal pipeline in security projects

This was raised from Slack (internal).

We should disable minimal pipeline because in the security project we reset approval for each pushes. This is explained in the above thread, quoting @engwan here:

Or we can just run full pipelines all the time for the security project. The other different thing there is that we have “reset approvals on push” enabled.

So if you push after approval, it will run a minimal pipeline, and then run another full one after it gets approved again.
