Delete LifecycleEventsAPI has a discrepancy for the 'dateTime' field. Should take an event ID as a path parameter and not as a json

Description

Delete LifecycleEventsAPI has a discrepancy for the 'dateTime' field. When a project is created and a lifecycle event is added it looks like this for example:

"LifecycleEvents": [
            {
                "name": "Create",
                "dateTime": "2024-05-03T13:15:36.228746"
            },
            {
                "Resources": [
                    "namespace:any-group-type--AnyIndividualType:SomeUniqueAnyIndividualTypeID:"
                ],
                "EventId": "eventId53",
                "DateTime": "2020-02-14T09:13:16.52+0000",
                "Name": "Example Name 02",
                "Remark": "Example Remark",
                "WIPResources": [
                    "namespace:any-group-type--AnyIndividualType:SomeUniqueAnyIndividualTypeID:"
                ]
            }
        ],

note the difference in the case for dateTime field.
The service uses the following field. public static final String DATE_TIME = "DateTime";

Also, I think the Delete Lifecycle event should take in a EventId as an input and not a json. This implementation should be re-worked.
