fix: add spark_web dependency_overrides to spark_cli test pubspecs

The openapi tests create temp projects that depend on spark_framework
via path. Since spark_framework now depends on spark_web (also a local
package), the temp pubspecs need a dependency_overrides entry pointing
to spark_web's local path so dart pub get can resolve it.
