[form_summary] Fails if there is more than 1 collection with the same name

[hellpe]

E.g. with Meyzieu (there was a sub-collection named "Meyzieu" in "Données confidentielles"):

Traceback (most recent call last):
  File "<string>", line 1, in <module>
    import sys; from importlib import import_module; sys.argv = ['make_summary']; sys.exit(import_module('data_utils.form_summary.main').make_summary())
                                                                                           ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^^
  File "/Users/laurent/Documents/Repos/data_utils/data_utils/form_summary/main.py", line 18, in make_summary
    collection_id = get_customer_collection_id(customer_collection_name)
  File "/Users/laurent/Documents/Repos/data_utils/data_utils/utils.py", line 102, in get_customer_collection_id
    return MTB.get_item_id('collection', name)
           ~~~~~~~~~~~~~~~^^^^^^^^^^^^^^^^^^^^
  File "/Users/laurent/Documents/Repos/data_utils/.venv/lib/python3.13/site-packages/metabase_api/_helper_methods.py", line 81, in get_item_id
    raise ValueError('There is more than one collection with the name "{}"'.format(item_name))
ValueError: There is more than one collection with the name "Meyzieu"

Workaround: be sure that there is no other collection with the client name
Possible fix: ask for the collection ID instead of the name
