Upgrade the RunsOn runner for sitl_tests and ros_integration_tests
from 4cpu-linux-x64 / ubuntu22-full-x64 to 8cpu-linux-x64 /
ubuntu24-full-x64 with extras=s3-cache.
Matches the runner_medium spec used by the sitl-tests and
ros-integration-tests jobs in the CI orchestrator branch
(mrpollo/ci_orchestration). Both jobs are compile-heavy and benefit
from the 2x core count. The ubuntu24 image and s3-cache extras align
with the house style already used by clang-tidy, dev_container,
docs_deploy, docs-orchestrator, and build_deb_package.
No other changes (speed factor unchanged, container images unchanged).
