ref(grouping): Remove unused properties in EventGroupingConfig type (#97404)

This is a follow-up to #97234, which removed some legacy attributes from grouping configs, since they weren't being used in either the front end or the backend. In this PR, the same attributes are removed from the front end `EventGroupingConfig` type.
