### Ionic Framework Version

v7.x

### Current Behavior

There seems to have issues with the `ion-datetime` component, when the time modal is **focused** and that we try to interact with it via arrow keys.

1. The hours does not seem to handle the current hour (that is, if it's 10 and then you press Up, it goes to 1)
2. When you continue pressing, it goes up to 19 and then goes back to 2.
3. Once it's back to 2, the minutes get incremented, but only 10 by 10

_Note : In my timezone, the time is 0-23 based_

### Expected Behavior

1. Pressing an arrow should make it move 1 hour+-, starting from the current input hour
2. I guess the input should goes up to 23, then goes to the minutes (but it needs a focus state ?)
3. When the minutes wheel is focused, it should respect the step entered (and not be only 10 by 10 at the beginning)

### Steps to Reproduce

I tried everything on the "basic usage" example of the `ion-datetime` component : https://ionicframework.com/docs/api/datetime#basic-usage

### Code Reproduction URL

### Ionic Info

Not applicable (https://ionicframework.com/docs/api/datetime#basic-usage)

### Additional Information

_No response_

Start with the basic usage example linked in the issue and reproduce the keyboard interaction in the focused ion-datetime time picker. Compare the hour, minute, and step behavior with the expected results described; done means arrow-key navigation starts at the current value and respects the picker bounds and configured step.
