Wrong type for half_day_start and half_day_end in response https://api.personio.de/v1/company/time-offs

[Vardaleb]

According to the spec:

api-docs/personio-personnel-data-api-oa3.yaml

Lines 4579 to 4580 in 2f3707f

	half_day_start:
	type: boolean

half_day_start and half_day_end are of type boolean. But the response in https://api.personio.de/v1/company/time-offs returns them as integer:

        "half_day_start": 0,
        "half_day_end": 0,

I expect them to be booleans instead:

        "half_day_start": false,
        "half_day_end": false,
