Auto-populate modules collection within temporary visiting/inspecting helpers

[pawamoy]

Is your feature request related to a problem? Please describe.
Populating the modules collection is important to be able to use all features (notably inheritance).
Helpers like temporary_visited_module and temporary_inspected_module do not populate the collection, so devs have to it themselves, in the tests. That leads to a lot of duplicated code.

collection = ModulesCollection()
with temporary_visited_module(
    """
    code...
    """,
    modules_collection=collection,
) as module:
    collection["module"] = module
