### Ionic Framework Version

- [ ] v4.x
- [ ] v5.x
- [X] v6.x
- [ ] Nightly

### Current Behavior

the previous version of ion-datetime has monthNames property. it was useful to set month names up for any app localisation even the app language no in localisation standarts. also we would like to set weekdays' names to any.
is there way to do that in ionic 6?

also there are many tiny uncomfy stuff, such as:
- imposible to set title for the component;
- ionChange does not change value property;
- does not show cancel and done buttuns even cancelText and doneText are set

### Expected Behavior

- must be title, monthNames and weekNames properties;
- ionChange must change value property;
- must show cancel and done buttons that. done button must emit iolDone event

### Steps to Reproduce

just like in https://ionicframework.com/docs/api/datetime
