Describe the bug
When creating a database item in Notion it only allows us to select one date which is the start date and we should be able to select start date and end date.

To Reproduce
Steps to reproduce the behavior:

1. Create a Workflow that Creates Page from Database that has a single Date property
2. Try to Add Start Date and End Date to the Date Property

Expected behavior
Notion Date Property

{
  "scheduled date": {
    "date": {
      "start": "2022-01-01T00:00:00Z",
      "end": "2022-01-02T00:00:00Z"
    }
  }
}

Current:

  date: {
    type: "string",
    example: "2022-05-15T18:47:00.000Z",
    options: () => undefined,
    convertToNotion: (property) => ({
      date: {
        start: property.value,
      },
    }),
  }

Future:

date: {
  type: "object",
  example: {
    start: "2022-01-01T00:00:00Z",
    end: "2022-01-02T01:00:00Z",
  },
  options: () => undefined,
  convertToNotion: (property) => ({
    date: {
      start: property.value.start,
      end: property.value.end,
    },
  }),
}
