DateTimePicker deprecation

DateTimePicker has been deprecated for a very long time (since @blueprintjs/datetime v3.2.0) and will be removed in v5.0. Its replacement is simply the DatePicker component available in the same package.

DateTimePicker → DatePicker

Simply replace <DateTimePicker> with <DatePicker timePrecision="minute"> (replace with the time precision of your choice). TimePicker props may be customized via timePickerProps, same as before.
