fix: return type for dashboard when include is used

[abhi1693]

Closes #

Proposed Changes

Briefly describe your proposed changes:
I have only updated the return type for the GET operation on the dashboard service. When the parameter include=properties is passed to the methods, even though the correct API calls are made, the returned object does not include cell properties.

To fix the issue, DashboardWithViewProperties is returned instead of Dashboard. Using this without include returns None for cell properties thereby keeping the original code intact.

Thanks for your PR 👍. There are a few requirements that should be satisfy before we accept the PR:

1. Please update CHANGELOG.md
2. Please add test for your changes into test_Dashboards.py. Something like following code will be pretty fine:

def test_get_dashboard_with_cell_with_properties(self):
    unique_id = str(datetime.datetime.now().timestamp())

    dashboard = self.dashboards_service.post_dashboards(
        create_dashboard_request=CreateDashboardRequest(org_id=self.find_my_org().id, name=f"Dashboard_{unique_id}_IT"))

    # create cell
    CellsService(self.client.api_client).post_dashboards_id_cells(
        dashboard_id=dashboard.id, create_cell=CreateCell(name=f"Cell_{unique_id}_IT", h=3, w=12))

    # retrieve dashboard
    dashboard = self.dashboards_service.get_dashboards_id(dashboard.id)

    from influxdb_client import DashboardWithViewProperties, CellWithViewProperties
    self.assertEqual(DashboardWithViewProperties, type(dashboard))
    self.assertEqual(1, len(dashboard.cells))
    self.assertEqual(CellWithViewProperties, type(dashboard.cells[0]))
