Set trigger: none in the CI tests (quokka-astro#1593)

### Description
This way, the GPU CI tests will only be tiggered via a manual '/azp run'
in a PR targeted at any branch. Commits into development branch won't
trigger CI tests.

Also added the submodules to the include list so that a pointer change
(the commit SHA reference) at submodules like extern/amrex itself will
trigger CI test.
