fix(ci): Use workspace-relative path for E2E temp directory

runner.temp resolves to the host path (/home/runner/work/_temp) but
inside a container the equivalent path is /__w/_temp. The copy step
writes to the host path which doesn't exist inside the container.

Use a workspace-relative path (dev-packages/tmp-test-application)
instead, which is inside the mounted workspace volume and accessible
from both host and container.
