Allow committee admin to also duplicate meetings from their own committee

[Elblinator]

Wanted behaviour: If the setting from here https://github.com/OpenSlides/openslides-backend/issues/2507 is activated then the committee's admin should be allowed to duplicate every meeting from this committee and every template into this committee. Superadmins and Orga-admins should remain capable of duplicating every meeting into every committee

[Elblinator]

The requirements changed: Everyone (superadmin, orga admin and committee admin) is only allowed to clone every meeting from this committee and every template into this committee
