Add ignore-regex for codespell to ignore possible "es" localizations

Otherwise ATM would trigger one already

    ❯ codespell -C1
    :                                 "en": "Several days",
    >                                 "es": "Varios días"
    :                             },
    ./examples/activities/activity1_embed.jsonld:52: Varios ==> Various
    :                 "en": "Several days",
    >                 "es": "Varios días"
    :             },
    ./examples/activities/items/item1.jsonld:41: Varios ==> Various
    : 											"en": "Several days",
    > 											"es": "Varios días"
    : 										},
