[TASK] Ensure using symfony container in tests

A couple of tests are adding services to a
container instance. Since the `ContainerInterface`
does not define the used `set()` method, the
tests are adjusted to explicitly require the
symfony service container, which provides
mentioned `set()` method.

Resolves: #103183
Releases: main, 12.4
